Considering a Corsica?

I have came across what appears to be a good deal on a 1990 Corsica LT 3.1. $200, but the car has a weak spark. Haven't had a chance to look at the car in person as the car is 125 miles away. I was wondering what may be the problem, and does this car have DIS or a distributor?

the corsica has a dis and the cause could be a bad coil pack or just as simple as plug wires. I bought my corsica for 200 and it has lasted for years. Mind ya there can be some problems but they r a cheap fix
