If you own or are considering buying a 2005 Mazda Rx8, budget for potential repairs before each MOT. Before your MOT, pay particular attention to brakes: Listen for squealing or grinding noises.

At 51,742 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
