Did I mess up?

[Jerrod]

I recently had first crack at a 220k 2001 corvette ls1still in the car, running and everything; electronics, all of the accessories, computers and such. I passed on it a 2 grand. The catch was I had to pull the motor. I thought 2k was fair if it was already pulled but being as though it wasn't I offered 1500. I didn't have the money at that moment but could have easily got it by the weekend after it was posted. Did I screw up? I probably would have had it torn down and rebuilt with that kind of mileage, so I couldn't just through it in my suburban.
What is a reasonable price for a high mile 5.7? How about low mile? I'm really new to the ls scene but I am pretty sure that is the way I am gonna go. Any and all feedback is welcome.
My son wanted me to put the banana in. Cheers.
