1964 Plymouth Barracuda Build CAUTION Resto Mod

The color looks totally different in the two pictures, which is why best to see a car in person. Looks like the p.o. added "cuda" with a Sharpie so people didn't keep commenting on his "nice Mustang". Figured that added $1K value. Looks like you got a reasonable price, and at least the seller didn't go crazy and attack you with a shovel. Smart that you let him haggle it out with himself, remotely. Most of your planned mods are bolt-on, so won't affect the OE value. The mini-tub and probably the tranny swap will involve permanent sheet metal mods.
