Look
This car looks really good outside. I don't think my pictures do it justice really, but I can't be bothered going to take anymore. Good sporty look. Must look great when flying down the M6 (all within the speed limit, of course).

Feel Inside
Comfy enough, though possibly not as comfy as I'd expect from  top of the range model, which apparently the Zetec is. Some of the interior is also a bit plasticky, but I can live with that. Definitely spacious enough.

Sound System
This is very good. Has a very clear sound with lots of options to get the quality of sound you like. Not sure what it is like in the back, but I suspect it will be as good. Also a consistent radio reception all the way.

Drive
The drive is normally very good; smooth and with sufficient power for long motorway driving. However, there are times which it doesn't appear to have the power it normally does, which can be a bit frustrating. This MAY be down to my crappy driving though.

Other
I'm a little surprised that this car doesn't come with more features, considering it's supposed to be a top of the range model. I really noticed not having auto-windscreen wipers (which I'm used to) when it was pissing with rain on and off. Still, these things aren't necessary.
Space wise there are no complaints at all.

Summary
I really like this car, and would be very happy if I got one every time I got a hire car. There is pretty much nothing that REALLY annoyed me, and on the whole, is very good. I doubt I'd buy one, cause 17 grand seems kind of pricey, but a good hire car.
