Nothing has gone wrong with the car that can be attributed to the vehicle.
Unfortunately the local Mazda dealer service back-up leaves a lot to be desired, as I feel does Mazda UK's. But the car itself is very reliable as have been my other 8 Mazda's.
I have to say that I agree with the comments about after- sales service and Mazda UK. They seem more concerned with selling new cars than maintaining the ones that they have already sold, and building a reputation. It is no wonder that secondhand values plummet. They are complacent and don't really deserve to have a reliable car like the 626 to sell. I have owned 626's since 1997 and currently have a 1995 Executive - a beautiful car, but with a few faults, especially the noisy HLA's.
