    This was our first GMC purchase, it was easy as pie thanks to Mike Foster. We went in Sunday and after a few hours the deal was done and the sale is ...complete??? The car was ready two days later! Mike spent an hour going through every detail in the car with us and was helpful in every way. He was available via text and phone the whole time. Highly recommend Mike Ans the GMC Yukon XL Denali we brought home!

  • Fabulous service department
    August 8, 2017

    Bought a new Cascada in May. Roof failed in a rainstorm in August. Had to park under a bridge because the roof would not come up. Finally was able to... get home after rains ended two hours later still with the roof down. Colonial took the car immediately and kept it safe out of the weather and worked with General Motors to determine what this unique problem was. They gave me a loaner car for the entire period. If service like this continues throughout my ownership I will buy from Colonial "forever"!
