My 2008 gt just turned over 63,000 miles.... yes in only 2 years of owning the car. I called a local private mazda mechanic to figure out what future servicing would look like. After he got past my mileage for the year, he did say it was possible to have some pricey maintenance i.e. timing belt, water pump... but Im curious to know what service histories other have had and if they were able to hold off on certain replacement maintenance parts etc. in lieu of my upcoming visit to have serviced. With seeing how well the mz3gt has held up both inside and out unlike my past vw's I'm curious about the longevity of the mechanicals. So any past experiences, and lessons learned- both good and bad from high mileage services and if there was anything you would have done differently given a second round- please do include that into this thread! I plan on keeping the car for the next several years and id say 100k miles for sure.
