These guys/gals at the Centennial location are awesome. I was told by Auto Nation Jeep Arapahoe that my Grand Cherokee (still under warranty) needed a new radiator and heater core to the tune of 2,500 dollars. Unfortunately, the powertrain warranty covers neither of those. I brought my vehicle here to get a second opinion, and was told that I do not need a new radiator. They performed the necessary work and I got out the door paying less than 800 dollars. They were very professional and honest, and I can't recommend them enough.
