Does anyone know if there are trip computers you can install into your car which do all the usual stuff such as how many miles left in the tank, average speed, mpg and so on.
The only reason I ask is because lately I've been driving my dads bmw and that has the little trip computer on it and it actually makes me drive really fuel efficiently because I try and get the number of miles left in the tank as high as possible while trying not to drive like a granny.
I'm guessing either there isn't such a thing or it's quite expensive and hard to install but it may be worth it in the long run as my 2 is/will be my daily drive.
Cheers
