Project or purchase? any advice welcome.

[TIATO]

Good evening!

I wanted to take a minute to get some advice on building a car vs. buying a car. I love to take part in HPDE's. I've had a 01 BMW M5 and a 01 Z06 that i have both tracked (mostly Mid-Ohio because of location). I am at the point in my life where i would like to step up to another vehicle as all i currently own as a toy is a 67 DeVille (cigar car) and i really miss the track. If i have a budget of 50K would it be feasable to purchase a 66-67 Chevelle and make it capable at a road course (please read comparable to either of the previous track vehicles i have had) or should i buy a C6Z or maybe an E60 M5. Obviously i would prefer the Chevelle but is it a reality to build a reliable track car for that kind of money?

I am not looking for a show car so the body will not be perfect. I have looked around and think i can get into one for 10 to 15K that would meet my needs as far as looks. I have also looked into frame swaps and find the Schwartz chassis very appealing. Im already at 30k+ and havent bought an engine. I look forward to hearing from anyone about their experience with their builds. Also i guess the X-factor... was it worth it when you went over budget? HA

Thank you so much.
