avoid the 1.9 diesel as it shares a lot of common components with the Alfa romeo engine that is prone to fuel pump and injector issues
I'd got for the 1.6 or 1.4 turbo as both have enough power to move the car briskly along

If you want a quick car the V6 turbo is very fast and excellent value 2nd hand
