My ten pence worth...
I love the Corrado's styling - its basically a Golf in an Armani, and as already said above, I'm sure they will be a serious classic in say ten years. I have therefore considered maybe moving to a Corrado for my next car, however, my only issue with them is the compromised engines...
1) 16v is relatively slow and apprently feels a bit weedy
2) The G60 ties you in to expensive G-Lader refurbs, and as its a more highly strung engine I would be constantly worried its going to pop
3) The VR6 is a delightful lump but would be much more difficult to maintain on a DIY basis due to the size/weight of the engine and cost of parts.
