Firstly, I am from the UK. As you may already know, fuel prices are extremely expensive here. £1.05 a litre which is about $2.00USD a litre. I currently drive an E36 BMW 316. (1600cc) I don't find the car to be very economical and I seem to be making very regular trips to the fuel station! Now my question is, is the BMW 316 the most fuel efficient petrol E36? Some people say that the BMW's with larger engines would be more fuel efficient due to the fact that they wouldn't have to work as hard. However, when I look at MPG figures on various websites, they do not seem to support that theory at all.
Also, a separate question, are the diesel E36's any good? I.e. are they reliable and quiet? Or are they just old, dirty and noisy diesels? I am looking for a replacement car and hope to have something more fuel efficient. It would be nice to have a BMW 330is and many of you guys probably think I'm strange for aiming for something slower, but fuel prices are just stupid here, and they're only going to get a lot worse when the government put taxes up on fuel by over 4p by next year, coupled with the anticipated price increase of oil!
