For Sprinter owners with Mercedes diesel engines: I bought a 10-year-old Sprinter-based RV and drove it here from Florida without having a pre-purchase inspection. Although nervous about what might be discovered, I took it to Quality 1 based on their reputation, professional YouTube videos, and their experience servicing Sprinter fleets. Their inspection was thorough and included test drive, visual inspection, fluid checks, engine, and all computer monitors. They turned up several areas needing immediate servicing for safety and maintenance of my investment. They were also able to advise me that the monitors indicated it would pass smog, which was a relief to me (and it did.) Add in clear communication from Scott and Jason, extra effort from the mechanics to work late so all would be taken care of by the next morning, helpful printouts, and no surprises in the invoice, to make a satisfying experience for me, with new confidence in using this awesome vehicle for my family and I, and well worth the drive from Vista to Temecula!
