You know I was driving around yesterday on the freeway looking and thinking of all the newer cars...What I came up with is the Vette's and Ford GT500's will probably start to rattle and fall apart after 60,000 miles, Merc AMG's end up in the shop regularly, BMW M's like Zuffen said the electronics and motor reliability is suspect at times, Ferrari's burn out fast, Porcshes end up in the shop regularly too, etc...etc.... If you proceed to hammer these cars regularly I would venture to think they would fail even sooner then described above....
I know my old Lexus is not a comparable car but I could honestly hammer it daily with nitrous too and I just knew it would never break down and chances were it would hold up for along time even with 100,000 miles already on the car....It did for 5 years until most recently.... With these newer cars I would not share that same confident fealing... With these newer cars, I would look for smoke after hammering it for a few weeks... So in conclusion I said to myself, Maybe the new Lexus IS-F series sportscar is a solid and reliable ride.... Why you may ask? I remember seeing that car on the dyno for the whole weekend at the LA car show, I mean it was constantly hammered and floored on the dyno machine minute after minute and still it ran and sounded perfect by the time the weekend was over.....
Fellas simply said, stick with the Lexus IS-F.. It may not look as good as the BMW M6 or be as fast but it will hold if you have a heavy foot like me... Because me thinks they are built to last........Yoda has spoken...
PS. Quick story - My buddy worked at the Porsche dealership as a mechanic a few years back and brought over a New Porsche Turbo, a $140,000USD car at the time...He said, "drive it hard and floor it as you please, this is my gift to you as it is your birthday", which it was... I never drove a turbo'd Porsche before let alone get to absolutely roast one, so I jumped on it....... My roast session lasted 20 minutes or so and by the time I was done with this little black Porsche it was smelling, burning up, and basically ready to give out if I continued... My buddy took it back to the dealership smoking and he got an ear full from the head mechanic as the car needed now alot of additional work..
It was very quick, light and handled like it was on rails...However, that little Porsche wouldn't last a week in my care... It would break down, no exotic's for me please...
