I've got a bit of experience - granted mainly with newer cars - and so when I drove the Corrado I found it distinctly average. The last one I drove was rattly, with a harsh ride and an interior that was falling apart. Sure, the steering was good and it handled well, and the engine was excellent, but for me it was far from the complete package you're making out.
The question is a difficult one on such a budget, and I'm not sure there is a car that ticks all of the boxes. Maybe some compromise is required.
However, I'd have the Corrado over an FTO every single day of the week. Hateful cars IMHO.
