A long out of date thread perhaps but you're welcome to come and have a go in my Ibiza Cupra diesel if you like?
160BHP and I get anything from 37-45 MPG doing a ton, 70 mile round trip daily. I'd say I'm still not used to it, it's strange all lag then a fuck load of boost but they're meant to be mental after a remap at around 200BHP. You start to stress the clutch, etc at that point and the replacement kit (I think inc. flywheel) is ~£900 so it's a good incentive to not go mad on mods
On the plus side it's got the biggest brakes out of the SEAT range (on the minus side it's £90 for the pads
as there's only AP Racing and Ferodo that do them- I'm at this point now, got to choose!).
All in all it's a good car, but I'd say deffo try a few different cars before picking!
