That car would cost more to register than what you paid for it.. so I suppose if in good running shape, which seems you got a killer deal on it since runs fine. I would sell it for a profit but if I needed another ride for around town, I would definitely keep it. With the cost to plate and insure it being much more than you paid for it, id sell it for a nice profit. You can easily get 500$ for it.. probably close to 1000$ based on your description of how it runs... If you can snag those for 100$... keep doing it and resell them for 1k... if you can flip one per month, up to an extra 900$ a month in revenue for you..
