If you have th chance to buy one, that means there’s a seller considering selling one. Unless the seller said “yeah, it’s for sale but toss me a price first” what starting price did the seller give you when you asked “what do you want for it?”
Clearly there is a dance going on but with no pictures, the price could be from $10k to $100k. Throw us a bone and tell us what the sellers asking price is.
More importantly, what are you willing to pay for it? We could suggest it might be worth $60k but if you don’t have $60k then what’s the point asking us?
The biggest issue in asking us for a price range is that you haven’t provided any pictures so we’re shooting in the dark more than you are since you’ve actually seen the car.
