The air conditioning is the only serious problem.
This an absolutely fabulous car to drive. Is it a sport? Or, is it a saloon... It's fun trying to figure out which.
In the past, I have owned a 323 SE hatch and generation 1 RX-7. This car continues in that spirit. I would highly recommend it except for one problem: the air conditioning doesn't work well in the extreme desert heat conditions of the Emirates. If you live in a hot climate, skip the Mazda 6. If you live in a cold place, have a blast!
I have a Mazda 6 luxury sedan and I find the climate control air con brilliant. I live in Australia where we regularly get 40-45 deg C days in summer and I only use the aircon in "eco" mode as it easily copes with a day that hot with the inside temp set to 23 deg. Sometimes I even have to turn the temp up a bit as I start to freeze. It has one of the best air conditioners that I have found in a car, even better than the locally made Holdens (GM), Fords, Toyotas and Mitsubishis which are designed for our climate. Maybe there could be something wrong with it??
