I've got a V 2000 reg, and i'll get around late 20s/eraly 30s, but it's different mpg when filling up from different petrol stations...
Bu major factor is your own driving technique, i realy don't give to much drilling in the 1st and 2nd gears, some people do, one of my mates got an IS200 on V plate and he's always complaiing about the fuel consumption, but he's got a heavy foot..
You have to look facts that it's got 2.0 Ltr engine, a big enough body n it's rear wheel drive... pushing rather the pulling..
It'l have to do..... ;) ;) ;)
