don't forget, emission from diesel engine is carcinogenic. i believe this finding is relative new. so if you are the type to park your car inside the garage, it might not be a good idea to warm up your car there.
i believe most, if not all, new VW diesel engines come with turbo. i am a VW fan, and i have been reading up on new Jetta turbo diesel and such. it is highly economical to drive these, if you commute long distances everyday. with their 10 yr/100,000 mile powertrain warranty, these cars should be virtually worry-free mechanically. but as others have said, owning a diesel car can also be inconvenient in some ways.
