I used to own a 2009 Rx8. Their Mazda 6 and upper models are a bit pricey but one thing I like is you can still get them in manual transmission.
Is the one you are looking at manual transmission? That seems like a decent price for the mileage. I bought the Rx 8 in late 2010, grand touring edition, 6 speed , for 19k and it had 7,000 miles on it.
Regular maintenance was cheap, I think oil changes at the dealer cost me $40. Brakes as well were not expensive, what was expensive was adding a quart of oil every other gas fill up because of the rotatory engine.
I traded it in because it was rear wheel drive and horrible in the snow. But overall I liked the car a lot.
Mazda's are pretty reliable. I know some friends that have had theirs for over 150k+ miles. Assuming you do all the required maintenance.
