We've had our Fiat for almost a year. It's a great vehicle for driving back and forth to work. We have just under 12,000 on it. Haven't had any problems with it at all! I average about 33mpg and that's on a 8 mile run through stop and go traffic.
We removed the back seat since it's actually two small for anyone to ride comfortably in, and I did a back seat delete on it. That gives us plenty of extra room for our two large mutts, or anything else that we want to carry.
Have not towed it yet, but will this summer. Hopefully my tow bar will be in sometime next week.
If you going to do your own oil changes, here's a great video that show everything you need to do:
