Hello everyone! I have a few questions and hope you can help me. I am about to buy a 2005 Sprinter with a 2.7L I5 Mercedes turbo diesel engine, I would like to know what is the MPG on this engines and what are the costs of maintenance. I work as a courier and have a 2500 Chevy Express van, business is growing and need a bigger vehicle. I run 3100 miles a week. I would really appreciate all the information you can give me. Thank you and be safe out there.
