Which 2.5 TDI are we talking about? The 5-cylinder one or the V6?
Both 2.5s
Earlier one supposed to do epic MPG.
Both available with quattro.
quattro 2.5 TDI vs Bora TDI? quattro every time. More so if it's the five banger as it's a mint engine and more so again if it's the wagon as you can fit like, a whole antique dealer in the back or something. And it looks much better than the saloon.
But then you might want to go hooning about the place, in which case the Borarse might suit better.
