Thanks Daox, and you're absolutely right and that is one of the main reasons I detest most modern cars, even the "small" cars are humongous!
I think my Accent is somewhere inbetween the bare minimum days of the early to mid 90s and today's "tanks" as you so rightly put it.
I think it'll mod well and I think aiming for 50mpg (UK) is a realistic and achievable target but I guess we'll just have to wait and see!
