That plus the "1500 miles since being put together" but no mention of actual mileage makes me hesitate on saying if it's worth asking price.
Unrelated to the above car, but I think I'm starting to see on bookface that some people are just so smitten over these cars they are quick to inflate the value. Things are often overlooked that wouldn't normally be and give the car value based on a few gating items (notch, 5-spd, any interior other than red) and overlook the things that really bring value to a car (modded/restored with quality parts, vs cheap eBay parts)
I remember looking at a driver last summer. Decent paint, nice wheels, decent shape. Got there and nothing in the interior worked. Broken trim, windows worked poorly, hvac blend door broke (just left on heat). Owner didn't care because it looked cool and sounded awesome and someone would buy it because of that. He is probably right
