Like I said diesels are my specialty. I am thinking of starting a thread with more info about them for others to understand more about them. As for diesel in the US time will tell. The biggest issue is consumer demand, consumers are not educated enough on what new diesels are. Mist Americans still think diesels are smelly, pollute and are noisy which is far from the case these days. There are many small diesel nozzles at gas stations in my area. Actually i would say 3 out of 4 gas station have them. The large nozzles are only put in at truck stops and even there they have the small nozzles available.
Oops I Forgot to answer your last question. I went the diesel route originally because of the powe and efficiency of them. I also liked how easy it was to add power to them. I've always Been a diesel fanatic. There is one gas car I would consider buying though and that is a suburu wrx sti.
