you know I think you hit the nail on the head, most persons critising the mpi probably havent driven one. Also it depends where you are coming from. That is i'm heavily into VW campers, hence the login name. I have just come back from 2 weeks in france with tent,kids, bicycle, trailer etc etc in a 1600 34bhp camper, got me around and did what i needed. The landorver mpi is 134bhp, so you can see a step up in power. Now I know the weight of the landrover is fairly heavy, however the old Vw's arent light either, so still an increase in BHP. Also the MPI is giving me 26 to 28 MPG and cost £800 for an L plate, I wouldn't get a TDi for that money and they only do the same MPG, so what the problem. and finaly not really intending on scaling a mountain in mine, so it suits me fine!
I'm bascailly running it cos it cheap and if I like it I will get a TDI, only cos I want to use Bio Diesel.
