My sister just paid 180$ for her driver side window, on her 88' buick lasabre. This was just for the track though (to keep the window held up), they said the motor would cost another 100$.
Replaced several door window regulator/cable assemblies in Buicks the past couple years. The cable connections break off and "bird nest" inside the door. Repair not possible. Replace the complete window regulator/cable assembly. Auto parts stores sell the units for aprox $100. Installation is easy.
