don't know the miles on the car but i doubt it would suffer from wires and plugs. You should be able to get there for less than $50. (i just got a set of delco gtp wires for $14 from rock on clearance pricing).

do yourself a favor ---- keep track of the plugs as they come out. they should, above all, look all close to the same. you'll learn a lot on how your car is running after looking at your plugs.
