Dropped in the dealer today and they told me that the woffle noise (sounds something like wingwong) coming from the back is the tyre noise. But it's weird that my friends one did not do it, we both have the same tyres (Dunlop Sport directional 215/45/17). Could the quality of Dunlop tyre vary within the same tyre model ? Can someone with this tyre hear the winwong noise in their car regardless whether the windows is closed or opened ? Thanks for any comment

That doesn't seem right, my seat heaters get to full temp in less than 5 minutes I only use them as they nicely fill the gap while the climate control gets up to full operating temp, which in fact is usually after just under 10 minutes....... As I've learned the operation of the heated seat is based on thermostat and the outside temperature. The duration is longer and it turns on itself often if the outside temperature goes below zero degree.

Mine one and the one I drove yesterday is from 2005. I think Sport Luxury started from 2003, not too sure. Just wondering whether the Sport is intentionally tuned to roar like the hell. As I was told the difference between the Sport and Sport Luxury is the full leather seat, 11 spoke alloy, HID head light and head light washer on the Sport Luxury model.

Have any "IS200 Sport" owners driven any "IS200 Sport Luxury" before ? If so, do you feel any difference ? Happened to drive an "IS200 Sport Luxury" from a friend yesterday. It was bloody quiet and comfortable compare to mine. Very low engine noise, smooth and the seat is very soft indeed. My "IS200 Sport" is about seven months newer but the seat and the back support is very hard like a rock that is killing my bottom and back after hour of driving. The engine noise is a lot loader even revs lightly. And most importantly is the "woffle" noise coming from the rear that really makes me headache and drives me nuts. With or without the windows open you can hear the noise coming from the back or coming through rear windows. The noise is really disturbing when driving at night, the noise is best observed when the car is going between 25 - 38mph (40 - 60km/h) with little or no acceleration apply. Does it also happen to your IS200 Sport or just mine that give this awful feeling

Whenever I doubt a car which might cause dent on my Lex I noted down the rego number and take picture if I have a camera with me. I always tried to leave a big space between my Lex and the other car in the parking by sticking my Lex as close to the wall that I have to get out through the passenger's door sometime, however a big dent still occurred one day on my return to pick it up ;) I managed to find the owner since it was in a hotel. It was a doctor and when he saw the dent on my Lex, his first reaction was like and shout like a gangster "This is nothing, look, plenty of dents of every cars. Have you got proof ? Did you see I did it ?". Anyway, that was logged with the local police that would give him a bit trouble though.

What is slim jim mate ? Can it be used for dent on the rear bumper ?

Thanks all, you guys are definitely more experienced in driving IS than myself and all the comments are terrific. To conclude, I would say that only 30% of people still like the old IS while 70% are going for the new IS. It sounds like I should keep the IS200 a little longer and enjoy its good characteristic before I lose it. Besides, IS250 has missed out the door pockets on the rear doors which is quite convenient that I need it sometime.

How often do we need power in general. I think a car with more than 153kW of power is more than enough for majority. The number of people who owns an IS300 from this forum is probably around five percent. This shows that the demand for power is very low indeed :D If I really need more power I would consider a GS rather than the top IS which is of a lower class and look similar to any other IS in the distance.

Why would they make all their motors this way now since high Revs will definitely cause engine to wear faster according to the rotation friction theory.

Do you use both Carlack68 (KLASSE AIO) and P21S Carnauba wax at the time, so which one goes first, thanks

Thanks guys especially Tango, tonyp & rap03 for the great input. The reason for the input is because I'm still fighting within myself whether to upgrade to IS250. I've got the IS200 from brand new a few months now, still way far from first schedule service. For the IS200, I just don't feel comfortable, soothness & luxurious when driving it, and with heaps of engine noise and exhaust noise tyre noise that drives me crazy ;) If I test drive the IS250 I might force myself going for the IS250 but I don't want to lose that much money just in a few months

Thanks guys for clarifying the unit value for UK & US gallon. No wonder some people in this forum quote way far more for their mpg (fuel consumption) than the others, probably one is referring to UK gallon while the other is referring to US gallong. Here's what I've came up with the calculation for UK gallon Miles Per Gallon to Litres Per 100 Kilometer 1 mile = 1.609344 km 1 gallon = 4.54609 litres If 1 gallon gives 37.2 miles then 4.54609 litres gives 59.8675968 km Hence litres per 100 km = 100 / (mpg * 1.609344 km / 4.54609 litres) = 100 * (4.54609 litres / mpg * 1.609344 km) = 282.48093633182215859381213711922 / mpg ie. L/100km = 282.481/mpg and mpg = 282.481 / L/100km (Thanks eXOBeX for the correction) Where mpg and L/100km is a number quoted for fuel consumption. Similarly for US gallon except that 1 gallon equals 3.785411784 litres not 4.54609 litres

I've learned that almost everything is better but how much better in comparison that you would score it.

Does anyone know the formula to convert between mpg & L/100km ? Do you guys use gallon as 4.54609L, 4.40488377086L or 3.785411784 litres in calculation ? Just wondering why it use miles per gallon for fuel consumption while the petrol pumping at the station measure in litre. Isn't it a bit hassle that one has to convert it to gallon in order to calculate for fuel consumption after each refill (If we want to know) :D

How much better is IS250 over IS200 in terms of the following priority ? Please do not include or compare the standard features, eg. stereo, interior light, auto wiper, keyless entry etc. 1 - Comfortable 2 - Smoothness 3 - Performance & Handling 4 - Feel of luxurious 5 - Fun to drive For the above five factors only, many percentage do you think that IS250 is better over IS200 ? Thanks for any comment :D

All service history and warranty for each Lexus is kept within the database. When a Lexus arrives at a dealer for service, they will type in the rego number that will reveal all the detail including warranty expiry date :D

Some fuses looks ok but is in fact blown. So change it all just in case and make really sure you check the right one.

V = IR, ie. current is directly proportional to voltage. Hence if the voltage reading is dropping so as the current. If the voltage reading maintains above 13.2 volts while the engine is running, your alternator is still in good condition. Try to observe if you can see any voltage drop while driving. If you drive the car daily and the reading drops below 9 volts while turning the ignition key then your battery is dying.

It's always better to go for heavy duty which lasts heaps longer.

The extended warranty is transferrable to second owner by completing a form and send it to Lexus Australia. It's always wise to have the extended warranty as it keeps the value of your car at the time of sale.

Is that a standard feature ? When the car is not locked and the engine is not running it would assume that someone is still inside the car that need breathing so it open an inch to let the air circulate

Yep, actual wheel nuts were loose @lex2005, have you jacked it up and wobble wheel with hand or have you fixed it ?

Never buy the first production car, especially this is the first IS being manufactured. Read HERE to get smarter for the future purchase.

The moral of the story is not to buy anything when they are new, not just for car. Anything first release contains heaps load of bugs including the Windows that you're running now. But if no one gonna buy the initial product then there will be no improvement and someone somehow will have to buy it eventually.

Believe it or not, I did all the calls and chase up when buying the current Lexus. They promised to ring me but never did in the end of the day. I've seen many complaints and compliments about getting the Lexus in other posts of this forum, it would be great that it all be moved into this thread and the link be sent to the management of every Lexus Dealers.
