I have this afternoon p/x my ISF in exchange for a M240i!
I only put 3000 miles on it, so it now has about 7200 miles. the colour black with beige leather (I have posted some pictures in another thread). Subject to a couple of marks (which no doubt Lexus will fix) the car is immaculate, no seriously it is. The rear seats have been sat in once in my ownership and according to the dealer I bought the car off, the rear seats have never been sat in. The car was serviced in June. However, the big service is up next, but I doubt if it will need anything. Tyres have lots of tread left. The dealer said that the depreciation on the car was running at about £600pm, therefore try not not to pay over the odds. I think it looks better than the red one Lexus have for sale.
I traded it in at Cooper BMW Reading, which is part of the Inchcape group. One of the Lexus dealers in that group apparently wanted it. I know dealers juggle around the figures, but the p/x for my pocket was £30k. That left me with equity for the BMW, I was quite pleased with that considering I only had the car 7 months. WBAC were quoting £29,400, before an inspection. I will be interested to see how much they mark it up.
It is an immaculate car, no thrashing, but there was the occasional blast of course (which has to be done). I hope it goes to a good home.
