So my Mazda6 is approaching 175,000 miles (5k to go), and was wondering if any of you all have any experience with high mileage Mazdas and if there are any maintenance items I should be paying attention too at this stage? I have been following the Mazda recommended maintenance schedule for the life of the vehicle.

I commute 75 miles to work, both ways, everyday at highway speeds, though I do a fair bit of stop and go driving when I get to the city as well as on the weekends. I live in WI and deal with pretty extreme cold temps in the winter (yesterday was -10°F when I left for work) and of course salt and all that garbage.

The car itself is running great currently, and I didn't have any identifiable issues at my last oil change, where they do a multi-point inspection. But, I'd like to get many more years of use from the vehicle, and feel I should start being proactive, and I can't help but feel there are some common problems that come with high mileage Mazdas that could be dealt with before they become a problem. Just curious about your thoughts! Thanks!
