That car came from the factory with a "100,000 mile" ignition system. Plugs, wires, Cap, (& rotor if equipped) should have all been replaced at 100k miles. If it wasn't you're severely overdue. Catch up on your maintenance that's behind, then re-evaluate the vehicle.
If your mechanic finds a cap or a rotor, do yourself a favor and find a new mechanic.
Do not believe everything you read on the internet.
