You have more information than I do. If they gave you an estimate, they have something in mind. You must find out what that is. For many years tune-ups have turned into nothing more than new spark plugs and an air filter. All of the other parts that were normally replaced aren't used anymore.
Spark plugs on a lot of cars are real hard to replace because ease of servicability is not what sells cars. Still, $500.00 is WAY out of line to just replace the plugs. That's why I assume they plan on doing additional work. The dollars you mentioned would suggest they are going to replace the timing belt to prevent very serious damage to the engine. I don't have any way of knowing what their plans are, but with the mileage, a new timing belt is good insurance.
