You can't change a leopards spots! One will like diesel, the other petrol... Personal choice... It would be better to test drive the differing models and make a choice! Loving the comments though!! There is something that fascinates me about the simplicity and power of diesel compression ignition engines. I don't really care that a petrol engine is more refined, can rev the nuts of it or that it runs cleaner. If I could afford a RS3 I'd have one, but I'd still have a diesel too!
