 So i posted a review about 6 months ago when i had about 2K miles on my Mazda3 SkyActiv and wanted to follow-up for any who is still looking into the car. After 12K miles I must say the car has been extremely reliable which was one thing I was worried about at first. I have had 0 problems and only maintenance has been the usual oilchange/tirerotation at 5K & 10K miles. Internally the car has held up GREAT! (i use the car for plenty of projects around the house and have been hauling all types of items) car fits anything in it. As for the engine, it seems to actually be running better after breaking it in, I recently got approx. 33mpg average on 950 miles of driivng about 25% highwy 75% city,
