I own a 1957 Plymouth Belvedere Should I sell it? If So,: How much?

before I answer your question,

Hey! marfanman!, the same wat 08 model years are on the merchant now in 07. Tough concept I know, but the auto perseverance has beautiful much always released the next model year the summer BEFORE the year in fact starts. Got it? no? too bad, moving on......

Yes, sell it, on me, now, also cheap.
Unless you have a specific reason you need to sell, it in reverse you just don't be sweet on it, I wouldn't. But my family has long amass also repair antiques, albeit your car is newer than almost I am used on working on (34 Nash, 41 Nash, 41 Buick, 58 Golden Hawk, etc....)

But if you did want to get eject connected with it, and it is clean, you might not be very much off on the value. I would check auto tradr also extra online sources that specialize in classic also muscle cars, and show what extra similiar cars are listing at.

But I would also keep it. Just my impression though.
