So the Mazda Dealership recommends to get a 30,000 and 60,000 miles preventative maintance done to my car. The work includes a laundry list of things they do or check on the car. I have 33,000 miles on my 07 MS3 and I am wondering if this is worth the 511 dollars they said it would be. Or should I just do the regular oil changes and the other regular maintanence work. Has anyone else got the preventative mainanence done to their car and do they feel a difference and was it worth it?? thanks in advance.
