Hi guys,
I've owned a lot of cars, most recently a Z06 Vette. I've always loved the look of these Cobras and have started looking into buying one.
I'd really like an unbiased opinion and some basic info on these cars. I've seen some that are built out of donor cars and others that seem to be more complete and just have a new engine and drive train installed. I saw a real nice Back Draft racing one which advertised brand new car. I know I want a big block and I would like EFI. I want something reliable. I've seen factory 5's and many others. What are the differences and pros and cons. I appreciate any feedback.
Thanks!
