tc-what? xxx-huh? you must be talkin about one o them big funny cars with too many cells...

Actually, what you said made me think of how many times I've read something like: "I raced my 12L3 for 3 seasons and then tried a new Fuzzwha 12 and boy what a difference!". Judging by how most guys maintain thier cars its no surprise that any new car would out-perform an old one.
