New to this forum and to the Merc World. We own a 2007 E-350 4-matic. We are pretty sure we have an oil leak (down a quart in a little over a month—no oil slick, smoke, or smell) and possibly something wrong with the front end (there is a light-sounding squashy rubber sound coming from the tires when going under 30mph—bumpy and smooth roads). Does anyone have a go-to mechanic in the Fairfax/Springfield, VA area who is NOT a dealer, is reasonably priced, and honest? Just had the Service A done at a dealer which felt like a rip-off. Thanks!
