Biggest reason, its a chev, i can work on it myself and the things i cant do, there is a really good chance that i can get it fixed most anywhere in any city..its cheaper to run and operate then a sprinter, although it does not get the mileage of a sprinter, i am working on that....and the original purchase price was as cheap as a well equipped extended CV.....
