Mazda CX7 2010 Used Automatic Gasoline mileage: 300 KM or more The car was fine and I took it to the workshop for a tune-up, and after that it didn't start. I took it to a well-known workshop and they said it's the computer. Its engine, gearbox, and air conditioning are excellent. I changed its engine and gearbox mounts and painted it completely and sanded it, but it still needs polishing. New registration. Inspection expired a month ago.
