There are tons of good and bad resons to choose a Diesel over a Petrol car, but to say that "i would never choose a diesel because of the smoke" is a stupid and childish comment! There are very few modern diesels on the road that actually do smoke! The small amount that do are probably not maintaned that well, so the same could be said for petrols that kick out nasty fumes when they aren't running right.
Also, if you owned a car that did smoke, so what? you're driving forwards and the fumes come from the back, so you won't be bothered by them?
The smell of diesels..... is this the smell of the fuel or the fumes?
The smell of the fuel i understand. it's not as nice as petrol but that can't be helped, and as your at the pump lewss often, its not so much of a big deal.
The smell of the fumes..... When? when i removed the CAT from my TDI it was unbearable and made me feel ill. i put the cat back on and have never noticed the smell of fumes once. Torque and MPG have been covered in dozens of threads, so no need to keep refering to it, but when people complain about the power delivery being in one lump, i can only assume they were in a badly remapped car, or they didn't know
how to drive it correctly as every VAG diesel i've been in has smooth delivery of power and puts other manufacturers to shame.
I would never rule out a petrol car, but it would have to be something special to tempt me from a decent diesel car.
