A few reasons really:-
Skoda Fabia vRS - nice but 5 doors put me off,
ibiza has a better spec and has a nicer interior IMO
Polo GTI - way too overpriced
Citreon DS3 / Dsport - Nice cars but seeing alot of them about, its a citroen,
Clio - was my previous car (not a sport though) too expensive to run / insure/ tax. also wanted a change away from a renault
Other reasons - rare car (never see many about), cheap to run, cheap to tax, cheap to insure (main perk), best looking of all the above, fun to drive, comfortable.
also as soon as i was thinking about changing cars and came across them and this forum, i instantly knew i wanted one (did come close to buying a punto abarth mind)
