Afternoon all, just joined Fuelly. Looks like a great site! I'm based in Essex, UK just outside East London.
Currently run a 2002 Audi S8 with 4.2-litre V8 and BMW Z4 2.2i, previously a newer 2007 Audi S8 with a 5.2-litre V10). Display in the Audi currently shows 21.5mpg but it achieves up to 24mpg on a run. The BMW almost always sticks to 35mpg.
I'm a chauffeur by day and drive quite a few different cars for work, New Range Rover, Mercedes S350 and S400 (hybrid) and others so may add these to my Fuelly profile too as I'm always filling these up. Looking forward to seeing the stats over a long-term.
