As the title suggest. I wish I had told him to stay away. 2016. 60,000 miles. $3700 repair bill. Vent valve and oil pressure valve? I've asked him to send me a copy. I asked him the history of the van and said it came from New Jersey. I'm guessing $2500 for vent valve and $1200 for oil pressure regulation of valve? I know cars break but this vent valve issue is unacceptable. If I lived above 37 parallel north latitude which is around Virginia I would sell any mercedes with this engine or move to Florida.
