  1. Good guide, but I agree with Herbie - see my thread: I imagine that the RX will be similar and that your cable is indeed crossing the curtain airbag which could interfere with its deployment. I'm sure that removing the A-pillar trim is similar to the GS, and would recommend it. Of course, none of us ever want the airbags in our cars to deploy...
  2. Yet the very site you link suggests that semi-aniline leathers benefit from the use of conditioners. I also like detailing my car and do similar research. I also have my own experience. For example, here's some seats in my father's BMW when it was 21 years old and over 140k miles. I was the primary detailer for that car and there's a reason that the leather was still pristine and supple at 21 years.
  3. Maybe they don't. However, Lexus use a number of unsealed leathers in their vehicles - for example, the semi-aniline leather in our GS Premier is not sealed (and this was evidenced by a patch of spew (look it up) that was occuring where a previous occupant's oily hair product had got on a headrest). This should be regarded as a benefit, because unsealed leather that can be fed can be maintained indefinitely - sealed leather will dry out and crack. Lexus themselves recommend the use of a conditioner:

    Has anyone used Rain-X?

    The glass cleaner products with rain repellent tend to be difficult to wipe off as you've observed, and their rain repellency fades quickly. Rain-X rain repellent is ok, but nothing more - I've moved onto Gtechniq G5, which is FAR better than Rain-X. Water beads even better, and it lasts many times longer (side windows and mirrors - I don't use on windscreen due to smearing).
  5. Depending on date availability this sounds like our kind of thing.

    Door pillar airbag cover

    I would imagine it's not terribly different to the GS: https://www.lexusownersclub.co.uk/forum/topic/118323-guide-hardwiring-dual-dashcam-in-mk4-gs450h-premier/
  7. As much as I tend to disdain the UK motoring press, and I should add that I have not driven an nx so this post is purely conjecture on my part, the reviews all tend to agree that the ride quality is poor. I tend to find that the American motoring press reviews tend to be more accurate and even handed about ride and handling than the UK (in other words, they don't swoon over M-sport BMWs that I find bone-jarring). The American motoring press praises the ride quality of the NX. There's a dichotomy here, as, if anything, you'd expect the UK press to be more forgiving of a firm ride and the Americans to call it out. So I suspect that Lexus fell into that old trap of tuning the suspension "to European tastes" in the NX that they deliver here. It seems to me that they avoided doing so with the LS, RX, GS and ES, while the more sporting IS will be set up that way anyway. Perhaps the appropriate lexus part numbers could be acquired from the USA, if an owner were so inclined.

    Residual values

    EV residuals are crazy at the moment because demand is so much higher than supply. We bought our Leaf 24 Tekna second hand in November 2017, from a dealer with 2 years warranty and servicing, etc for £11k. I've put 10k miles on it since then (up to 23k from 13) and it's still worth around £11k. The other Brexit driver that might influence that is if the pound does go south and makes oil more expensive for us to buy then petrol/diesel prices will go up again - again bolstering EV residuals.

    Tahara seats. Any good?

    It's probably very similar to the material that Tesla use in their vehicles (being from california where leather is a dirty word they offer no real leather at all anymore) and what Mercedes use (artico).
  10. I agree that the entire picture needs looking at. However, it makes an unfair comparison because when talking about petrol vehicles and we talk of g/km and mpg then we're talking about from the petrol in the tank - you're not counting the 11% energy overhead in refining (ie for every 9 litres in your tank, the energy equivalent of another litre was burned at the refinery in process heat), the energy used to transport crude from the well to the refinery, the energy used to transport the petrol from the refinery to the petrol station, the energy consumed by the petrol station for lighting, pumps, etc. The majority of UK electricity does NOT come from gas. Gas is the largest contributor at present, but at 41% over the past year it is NOT the majority. Petrol engines are at best 41% efficient (http://www.thedrive.com/tech/18919/toyota-develops-worlds-most-thermally-efficient-2-0-liter-engine) and only under VERY specific circumstances of load and rpm. That efficiency is also from fuel to crankshaft, and more is lost in the transmission and powering of ancilliary devices - at best 35% reaches the wheels. https://cleantechnica.com/2018/02/19/electric-car-well-to-wheel-emissions-myth/ https://www.theguardian.com/football/ng-interactive/2017/dec/25/how-green-are-electric-cars That comparison compares to generating electricity from oil, which is one of the worst way to generate it from a CO2 perspective - over 1000g/kWh. 2018 UK average was 218g/kWh. Current real-world average for EVs is from 20-50g/km in the UK, whereas ICE are anywhere from 100 (real world, not EU fantasyland figures) to 300+. Compare like with like, in other words compare an EV at the high end of that scale (Eg Tesla model X P100DL is around 45-50g/km) to a vehicle of comparable configuration and performance (lamborghini urus, 325g/km) and it's not even close. Please show these "all official estimates"? https://theenergyst.com/millions-electric-vehicles-sooner-predicted-no-sweat-says-national-grid/ https://www.nationalgrid.com/group/case-studies/electric-dreams-future-evs As you can see, national grid see a requirement for 35-40TWh of additional power to support EVs. http://www.mygridgb.co.uk/historicaldata/ We've cut annual electricity consumption in the UK by 46TWh since 2012 - and that trend is continuing. In other words, we've already CUT electricity consumption in the past 6 years by MORE than is needed to support EVs by 2040. On this we are in complete agreement - ever since the CO2 based tax was introduced it has been a complete and utter shambles. There is one VERY simple way to handle the tax situation - one that is completely fair in that it DIRECTLY taxes heavy emissions users and goes lightly on low mileage drivers, one that doesn't have loopholes (like people paying only 6% BIK tax on a PHEV that they never plug in and don't care that they get 20mpg as a result) and one that would have extremely low bureaucratic overheads - simply add the tax on the fuel. Political suicide, but the only fair and valid way.
  11. The general technical standard of driving in germany is mostly very good, and much higher than the UK. They do things we would perceive as very aggressive but they are the expected norm there. Once you have your head in that space and drive the way that they do then it works and works well. Generally german drivers have very good awareness of their vehicle and limits and pay better attention to their driving than UK. Unrestricted speed is to the germans like the second amendment is to americans - they can't really justify it but will fight tooth and nail for it. However, the geography, size and population spread of germany better lends itself than the crowded UK - some of my german colleagues (we do a lot of business there and have sales offices in Wiesbaden and Munich) think nothing of commuting 200km each way daily ("less than an hour on a good day").
  12. I once took my Volvo to 126mph (202km/h) on the A48 somewhere between Koblenz and Trier. Coming back down in speed afterwards 90mph felt like it was very slow - If you're giving it your proper concentration (as of course you should and must at those speeds) then your brain works fast and "normal" seems very slow indeed. It is something that would be very tiring to do for long periods, and I'm sure many don't give it the attention and concentration that it deserves (and we can say that of all driving). We will do so with our GS at some point.
  13. Try Gtechniq G4 - it has proven very effective at removing strange contaminations on ours. It is not just an abrasive polish, but appears to also be chemically effective. Apply using a microfibre for best effect.
  14. I found that AG glass polish worked ok-ish, but Gtechniq G4 was WAY more effective - wow, never experienced anything like it with any of many glass polishes that I've tried.
  15. Today I was giving the GS a wash, and discovered that it shares an annoying design flaw with my Nissan Leaf. The rear arches are shaped in such a way that they gather up huge amounts of mud and junk: Hard to see from this picture exactly how much junk there is here, but you literally scoop it out: Leaving your just washed alloy looking like this: And then use the hose and a brush to actually get it clean: Yes, I know I missed a bit!. You want to get rid of this mud - every time you drive in the rain it will rapidly get soaked through with water, but it will take hours or even days to dry out again (was dry on ours because our car is garaged and hasn't been driven in the rain for a while) - it will keep the metal damp and promote rusting. I'm inclined to spray this section (on both leaf and GS) with waxoyl spray: https://www.screwfix.com/p/hammerite-vehicle-underbody-aerosol-seal-black-600ml/6221h This should provide protection against stonechips and moisture in this area and hopefully prevent rear arch corrosion from setting in for longer.
