I have a Toyota Celica at the mo which has been cheap to run, great to drive and very reliable. When I started looking for another car I didn't want anything that was less reliable. Looking at things like the JD Power survey there were only 6 cars above mine, the Lexus was one.
I was generally looking for a car that was more executive with a smoother ride and more power. The test drive was great and I was very impressed with the speed of changes of the auto box, better than the other marques I drove. So all in all it was comfortable, fast, looks good and hopefully will be reliable, nuff said !
