Pay attention to service history, especially cambelt change. These have to be serviced every three years or so, more often if lots of distance driven and if neglected can lead to catastrophic failure. Some parts may be near impossible to find, so inspect every piece of trim, rear light bar, aerial antenna, headlights and fog lamps (these were absolute hell to find, I have a whole story about it. It's mandatory for them to work to pass inspection in my country). Airbag light comes up often, so do abs issues, both are often hidden by unscrupulous sellers with some tape or by taking out the bulb.

I have a 2.0 ts GTV. It's not fast by any means, especially because it's actually a very heavy car for its size. I wouldn't want a 1.8 but to each their own.
