I'm a big girl and don't have access to any private roads, thus I have never done more than 70mph anywhere. So I am going to buy a Diesel next time as I won't miss the 8mph difference.
It's funny you know but I've just realised, thanks to this thread, that whenever I'm driving a Diesel (some days at work) I drive it quite quickly but when I'm driving my Golf I try and coax mpg out of it rather than speed. I think my wires are messed up but at least I'm not paying for the Diesel.
It's a 140 TDI for me next I reckon.
