Just bought a 95 dodge intrepid..QUESTIONS!! Help

Hey guys, well i just bought a 95 dodge intrepid es for 1600. It had 145thousand miles on it .. which sounds like trouble to me but i talked to some others and they said i should be fine as long as i dont go on long road trips. eek. anyway the seats in it are electric and it would slide up but not as far as i need it to go it gets stuck on one side. My boyfriend said i need a new seat track .. know anywhere i can find one? I have more questions just not the time to ask and i'll see how this goes. Please reply someone :-)
Thanks
Ashley

you can find seat tracks at most junkyards, that's the cheapest way to go.
