Advise: Going to look at a scamp

$9K seems really high to me for a 74 Scamp.
Maybe if it was an earlier year Scamp, Duster or Dart...maybe with the running gear

I think that is more like a $5K car tops... and that is IF it is a real runner. My opinion only, of course...
The price may be high but add up the money you'd spend to duplicate the car. A solid body, great paintwork, 360, a 4 speed (Have you priced the cost to buy everything to swap to a 4 speed setup???) 8 3/4" axle, a nice interior...
You'd easily be over $10,000 building another like it.
These cars can handle quite well with a 1 1/8" front sway bar, 1" torsion bars, 5 stage leaf springs and a 3/4" rear sway bar and a set of Bilstein shocks. The cars are light and nimble with this combination.
