Currently run the (once) most aerodynamic production car in the world as a daily, 1991 Audi 100 avant, 2.0, five cylinder petrol. It gets well over 40mpg, which is quite amazing given it's age and size, it's quite big!
The first car which will be chopped from the fleet is a 2.7 twin turbo V6 petrol Audi allroad quattro...

I need to shift two adults, two kids, a pushchair, loads of baby wipes and sometimes a tent. The choice seems endless.. Do you get a tiny car which runs on fresh air, for school runs, shopping (50 mile round trip to the shops here in the stix) etc. and a big car for holidays and such things, or an 'all-rounder'? Having been used to the size of the old 100 inside anything we buy will seem cramped, sat in an octavia recently and it felt like a 1960s mini in terms of breathing space.
Any ideas on a reasonably economical jeep type thing also? We do get snowed in, mudded in, potholed in, etc. a tougher cookie would be no bad thing. I've looked at kia sorentos, jeeps, but you're struggling to get above mid-30s out of most of the things I've looked at. Or it it all in the driving technique?

Anyway, cool site, will keep me reading for a few months! Good subject matter also.
