As above, without knowing the model its difficult to say!
If its a 1.8 16v or Williams that has the wide arches then you can get 17s on running 205/40/17 tyres with minimal hassle. If its a normal body then youll struggle to go bigger than 16" wheels with 195/45/16 tyres on.
For looks, go for the bigger 17s. As a compromise between looks and acceleration/handling, 16s are the best.
Thats what I reckon anyway!
Oh, and hello newbie person!
