LOL!!
This guy is a friend of mine and drives car #63. It runs in the ITS class. This car is a front runner and has run the same engine for 8 years now. It has never been open and he races full seasons throughout the southeast. He is fighting for second in this pic.
These are faster than a IT7 or ITA car but both will provide you with a good reliable car that will need little work. Of course I would prefer to have one built instead of buying someone elses car. The initial outlay will be more but the long term expenses would be much less.
I prefer the 2nd gen cars over the first due to the IRS on the second gens. The 1st gens as you probably know have solid rear axles. They handle amazingly well, but, a well setup second gen is just amazing.
I hop this helps.
