SPF at a local used car lot

[olddog]

I was driving buy a used car lot today and spotted a Cobra. I checked it out. It is Superformance origonally sold in 1999 as a turn key minus for just under $35K according to the paper work. It recently had a 351W stroked up to 418? Dyno sheet about 525 - 550 hp range. Papers showed $14K for the engine. It didn't have knock off wheels, but they look similar. He said something about having centers that were not on them. I'm thinking they are the five lugg look a like wheels with fake spinners not on. Car is in nice shape to look at. He was closing and I didn't get a chance to look real close at everything.

Price is $43K.

Since we are only 1.5 hr away from London, I told him he should take it there. He said he plans to, but he likes it so much he isn't ready to sell it just yet. I told him to raise his price if he doesn't want to sell it. He acted like he already had done that.

It makes me wonder just how little does he have in this car? What is the ball park worth of such a car?
