Pre Owned 2019 Yukon Denali

Reviewed by BJBF from BLACKWOOD, NJDecember 02, 2020

Wow, this dealership is TOPS! We looked at many pre owned vehicles and the dealers were not investing in their used and pre owned vehicles. But, GreenBrook certainly does. New tires, brakes, everything is top notch! Prices far surpassed others that we looked at and I would highly recommend !
