Trying to buy a truck and need good advice

Here’s my dilemma. I am looking at purchasing a 1997 Chevrolet 1500 Truck with 124,000 miles for $7500. Or a 2003 Nissan Frontier 5 speed 4 cyclinder with 157,000 for $7400. I like the chevy but the v-8 and gas seems like it will be a bit much for my driving. The four cyclinder nissan has a 157,000 miles on it and that is my biggest concern. Please help me make an informed decision.
