Would be the Volvo for me.

I had a V70 D5 and it wasn't too bad, and that was only the old 160bhp version. Shed a few kg's and add some more oomph and it would probably be quite good. Can always add a few modifications if you feel like it too. I'm sure with a remap you can be in the order of 220bhp quite easily.

The Saab is just an old Vauxhall underneath. The Volvo is a Focus, which is a better start at least, and the D5/T5 are both Volvo's own engines.
