This is our first Mazda and I'd say I am very impressed so far. It's in the same class as our 2014 Kia Optima SX-T, and they share a lot of similarities - very smooth ride, attractive interior and body lines, great fuel mileage (the Mazda6 gets better mileage than the Kia), and plenty of passing power out of a 4 cylinder, though the Mazda6 is naturally aspirated and the Optima is turbocharged. I can't say which I enjoy driving more, both are a lot of fun and seem to be well put together.
I just bought a 2009 Mazda 6 Grand Touring i, and and overall am quite happy with it. The car looks modern and attractive, is spacious, comfortable and economical on the highway. It also has many standard items that cost extra elswhere. My main complaint is in regards to the quality of the interior plastics, especially on the doors and the driver's side of the dashboard. The handbrake should also be leather, as it is on the steering wheel and gearlever. The glove compartment's handle is especially cheap and is a long reach from the driver's seat. The ergonomics can also do with some rethinking - the button controlling the average/current fuel consumption, miles to empty and clock is hidden behind the steering wheel and whoever placed the trunk release button next to it should be fired! Twice I opened the trunk when all I wanted to do was change the display. Also, why does Mazda not have the central locking lock the car automatically when it exceeds 5 or 8mph? The 2.5L 4 cylinder engine feels gruff when pulling away and sometimes underpowered but is economical. I'm averaging 26.5 mpg on my 87 miles roundtrip commute to work. Rearward vision is restricted, but that's a small price to pay for the sexy looks, and the blind spot warning light on the exterior rearview mirrors is a bonus. The automatic wipers and headlights work well and not having to fumble with a key to open/start the car when your hands are full of groceries or kids stuff is welcome. Overall I prefered the Mazda to the Accord/Altima/Fusion/Camry I compared it to, but would be even more of a fan if the quality was improved and the engine had a few more ponies under the hood!
So I got this car mainly for its looks didnt know how it was going to pan out for me, but i love how comfortable it is, the drive is great, its got a good pick up however it isnt a sports car. everything I need fits in it nicely. I have long drives to work and so far it has been absolutley amazing. I would like a little more solid feel like my last car but this just seems to be the right fit for me for this time in my life.
