Should I get rid of it?

[snea]

I have a 95 Tsi AWD, blown head gasket, cracked head or block, I replaced the turbo with a used stock unit, paid 500 for the car with the junk turbo, and have a total of about 1100 total into it now. It leaks anifreeze into the crank case, and the oil/antifreeze mixture into the # 1 cylinder. The front spoiler is broken, there's a good scrape on the rear bumper, and there is one small place on the right side door that looks like somone opened it up right into a bolt.

I want to start rally racing but I don't know whether to continue and fix up this car, or sell it and buy a running 1g.
