If you drive a great deal over longer distances, that is the argument in favor of it. Even with the higher price per gallon it pays out.
You'll want to research reliability as well as repair costs. Look very closely at the warranty to make sure you understand exactly what is covered and what expectations are upon you as far as maintaining warranty coverage. Keep records of all routine maintenance and don't blow past the recommended service intervals, if you want to be sure a costly repair will be covered with no arguments.
They're fairly expensive to repair, is my impression. The urea in the emission control system has to be replaced periodically and can be expensive too, I understand. At least it was when I last looked into it, I was interested in a Jetta TDI wagon a little over two years ago.
Not trying to scare you off, just want to make certain you go into it knowing what's what.
What sort of deal are you getting on price, If I might ask?
I think we could look at 23K for 2 door
The DEF urea (aka “cow piss” to industry insiders) is about 12 bucks a gallon at WM. Similar to motor oil prices.
On big rigs it is consumed at about 2% rate of the diesel fuel consumed. Not sure about the VW.
