I absolutely love this car! I had always planned on getting a VW Beetle but DH saw the Fiat Pop on Top Gear and suggested we take one for a test drive. I hadn't been driving long and immediately felt happy and comfortable behind the wheel. For a small car you are quite high up so don't feel small. Although mine has a teeny engine it is a light car and still pretty nippy. I don't push it much above 70 but it can do 80 smoothly enough. I've heard they get a bit rattly at 90 but I don't drive that fast. :)
I( have had it for 3 years now and apart from new wipers and a valve for the windsreen washer it has had no problems at all. Economical to run and reliable.
It is small but as a second family car it is great. We can fit a weekend's worth of stuff, 2 adults, a kids and a small dog in (just) but it would be no good for camping.
It has been compared to driving round in a retro toaster but in a good way.
I drive on country roads, city roads and motorways and it is great for all purpose and all weather driving, although off road or in extreme weather I imagine it wouldn't be much cop. ;)
There are cheaper small cars but I don't think they are as nice. If, like me, you need to love your car (and even give it a name) this is the one for you!
