Actually I wanted a Porsche 911 when I was 16

(didn't get one though, I was too poor)
This 300D is my first venture into diesel (and first Mercedes), and I got it specifically to play around with biofuels. I heard that 123's were pretty easy to work on and convert. So far I've found it pretty fun to work on, and it does make me feel a little like a teenager again to have my feet sticking out from under a car again

I've kind of gotten swept up in the Benz experience - I think I'm hooked
