Nice! I bought my 2007 Mazda 3 i Touring new 5 years ago this coming June and I absolutely love it. I've put 93,000 miles on it so far and have done nothing but oil changes and a new set of tires. I replaced the spark plugs last week because the manual said so.
As for the interior quality, mine has the older style interior and I have no complaints. There are no rattles and everything still looks like new.
Mine has the 2.0 L and I average about 35 MPG with the 5 speed. I don't drive like a grandma either.
