Broke Turbo Talon

I'm looking into buying a turbo All-wheel drive 1991 Talon. My friend ran it into the back of a truck about 6 months ago since left it in his back yard. He sez it wont go over 30mph w/o sputtering and shutting off. Any Ideas?

It could have knocked one of the intercooler lines off. This will cause the car to sputter and you won't be able to drive fast at all. Check them out and let us know.
