Thats a very well done car with alot of high end stuff on it, whoever restored this car took the high road everytime. Who knows if it will bring $15K, probably not, one thing is for sure though, you probably couldn't restore it yourself with that level of parts used on this car and be under the $15K, if someone ends up getting this car for say $10K or less compared to restoring they have saved money.
I tell you guys the same thing I told the MGB guys, as long as you think your cars are worth nothing, they will be.
