It depends on if you have kept up on your scheduled maintenance up until now. First, check your owners manual to find out what services are recommended for your specific vehicle and how often. If you had your plugs and wires changed at the 100,000 mile marker, you may be nearing time to do that again. It is always a good idea to have your tires and brakes checked out. The summer is also a good time to check the condition of your coolant and make sure the entire coolant system is working properly to prevent overheating.
