After 3 weeks with my new (to me) '63 IS300h Premier, so far very pleased with it.
The feeling of "luxury" when sitting in the car is fantastic, the leather soft and sumptuous, the ventilated seats great in this weather (if a bit feeble) the sunroof (yes very rare!) is lovely, providing light to the cabin, which is bright anyway with Ivory leather.
The drive is sublime, incredibly refined, compared to my previous diesel, and the economy seems to be around 50mpg.
The downsides are the infotainment system, with regular crashes, unable to answer incoming calls, and complaints of echos but apparently only for the first minute or so, my previous £200 7 year old Chinese unit never crashed and was far simpler to use, with house numbers being able to be entered when postcode search was used.
Is it possible to mute the sat nav when using the phone?
The only other niggle being a rattle seemingly from around the sat nav unit and dash, which hopefully will be solved by the dealer, my 9 year old Hyundai with 117,000 miles was rattle free.
Overall, though the car is fantastic, and really has a feel good factor, the best thing about it being it's exclusivity - it is not a BMW or Audi!
