From the pictures it's hard to tell -- if I had to guess I'd say more than 150 miles. But since the quality of the pics is low, who knows.
I'm saying you didn't get the deal of a lifetime, nor did you get screwed.
As for the SS brake lines, I am purchasing mine from Maximum Motorsports. Some things I don't leave to chance or no-name brands ... braking is one of them .
Yeah, I got some 17x9, 17x10.5 Cobra Rs(replicas) waiting for tires. When I get time to do this(brakes) I'll get tires and throw everything together at once.
