Curious- base coat vs acrylic urehane for base

I have thought about trying to get another one.
My current projects are a 62 Lancer and 62 Dart. I did the body /paint on both last fall, Both good drivers, some new stuff like tires, Am Torq Thrust rad and carbon one of the The White 79 is priced at $4200and the RR at $4700.
99% of the inquiries are : are both them total of $4200. Would you take $2000 and a motorcycle? Are these Chevies!!! lol
The 79 was a never any rust 94000 mi car. The 76 had the usual Tx rust, all cut out and replaced. The 79 has perfect door panels and both have perfect back seats and headliners, both have the usual dash cracks, both need new door weatherstriping. Both has a set of painted rear window louvers I did not install.
Anyway if interested I am glad to discuss them.
