I read and understood your post and agree that diesels are far from what they used to be but........ The only emissions testing I care about is done with my nose and lungs
While I agree that the MB diesel is much quieter I doubt the Toyota version will try to match that. Afterall it is going in a TRUCK and Toyota probably won't want to pass on the extra cost to consumers.
Hell look at the set packages they offered in my Tacoma
I would have liked a V-6 choice as well as alloy wheels and outside air temp but that only came on a Pre-Runner so........ I settled.
Still happy with Toyota this is my 9th or 10th one but sometimes they just forget about you unless you buy the top of the line model which is probably where the diesel will be available in the US.
