My husband and I have been loyal customers of Cornerstone

Reviewed by Jenn O from Tewksbury, MAJuly 24, 2025

My husband and I have been loyal customers of Cornerstone Mitsubishi for more than a decade, and for good reason: they offer fantastic cars and have a team of professional, friendly salespeople who never make us feel pressured. Tori, Bill, and Will were exceptional; they were so professional and a pleasure to work with. As we were concluding our leases on our 2020 Mitsubishi Outlander Sports, we decided to lease two Outlander PHEVs, which we hadn't even considered before. Tori and Bill provided us with valuable insights on the impressive performance of the PHEV and explained how it operates. Personally, I don't believe New England is quite ready for fully electric vehicles, but I must say the Hybrid is an excellent choice. Having both electric and gas options turned out to be much better than we initially thought. We are extremely satisfied with our new leases. Thank you, Tori, Bill, and Will, for guiding us through the leasing process and making it so easy. We look forward to seeing you for maintenance and again in three years when our leases are up!
