Mine is a 200 Sport 99V, I brought in with Lexus as the prvious owner and I've had it for about 18 months now.
I first got the HeadUnit replaced under warranty - with no arguments, and only money I will have spent on it is for a near side wheel bearing, as it is going in the garage on Friday to have this fixed.
I've had 2 MOT's and 2 Services so far but other than that (touch wood) its not cost me anything else.
I would definetly consider another Lexus, dealership seems spot-on everytime and they are real high quality cars, built to last. Mine had 78k on when I brought it, but I've only done about 8k on since I had it, as have a company car. But even now with 85+ on the clock, it runs sweet. Start first time, every time!
and I've just got a DVD Player hooked up to my Sat Nav screen, which will keep me amused for a while.
