Mazda 6 - How is it?

Greetings,

Any comments on how a Mazda 6 2007 or 2008 model is? Is it worth a buy? I loved the looks and power with economical pricing. I dont see much of these on Doha roads, Why is that? They told me coz of bad after sales service and they really are not bothered and just running the showroom here for namesake.

But my concern is, how is this vehicle? Does it give running problems later? Heard the parts are expensive. But will a new car have any issues for 4 - 5 years?

Is the 2008 model out? If not, wen would it be out?
