Some yes, some no.
The GrassRootsColt went 10.9@128 on literally nothing-it now has more money in body repair than anythign else, but hell its 100% mint. Show quality work at this point. Hell, I itemized when was in my pile when I was trapping 150mph an DDing the POS. I miss it to the point that I am an inch away from building another.
I think it takes skill more than money to make a car fast. Im sure you have seen MANY instances where people have pelted their Vette/RX7/Stang/Whatever with their credit card, just to have it blow up, eat motors, catch on fire...ect. On the other hand, you have seen Joe Dirt in his rusty beat Camaro going bottom 9's on a junkyard BBC and a Holley 850 he found in his barn.
In the end-I see it as "No amount of money cant fix Stupid"
