The Lexus concept is worth buying - but I prefer the BMW M3 GT and the Audi A4 myself. I consistently get better times on the Ring with the latter two, with the BMW just barely beating the Audi out. Also, if you can pick up the Audi R8 (LMS I think?), it is fun as well. I like the looks of it the best and it's all wheel drive keeps it on the track even with two wheels in the grass on the turns. Lasltly, the Audi A4 sounds like an old VW bug with a cold. LOL.
