A very cool car.
But facts are if you're looking for reliability get a Toyota.
A 1968 mustang fastback shelby (My dream car) is for a select few who appreciate the beauty of it.
It doesn't handle like a newer car, it's loud and noisy inside and out.
The cost is about $250,000 in mint condition if babied since the day it was made.
I'm sure you could find a half reasonable good one for $60,000+ or a fixer upper for less.
They do make clones of these cars.
These guys have some nice ones http://www.cars-on-line.com/mustang_2.html
