I've been posting here about swirl flaps and high pressure pumps without introducing myself. How rude of me! Anyway, my name is Tony - I live with my family in a glorified shed with an aluminium roof (don't ask) and spend as much free time in the summer as possible on boats. This gets in the way of all the things we should be doing to the family shed. I mean, house. In need of something diesel with a decent amount of grunt for hauling boats up slipways, an M class seemed a good fit to replace our aging Saab 9-5, so here I am. We also haven't bought a drop of forecourt diesel since we started making our own biodiesel back in 2008 (well, OK, we ran out of homebrew in Europe once and had to top off with diesel to get home, but that doesn't count).
