I bought a new 2009 Mazda 6 with 45 miles on it. I have been a shade tree mechanic since I was 14 years old, I am now 58. I have done all my own maintenance on it the Mazda 6. I paided off the car in October of 2017. In December of 2017 seven days before Christmas a guy ran a red light and totaled both cars. My Mazda 6 had 550.000 miles on it and was still running like new. The only thing I had to replace was the transmission which went out at 350.000 and the front suspension, and a couple of batteries along the way. That engine was still good as new and did not smoke a puff, even with the petal to the metal..lol. I love that car so much I bought a 2017 Mazda 6, that now has 202.000 miles on it.
