I just got my 05 Envoy and it is AWESOME.
The price was very reasonable.
FANTASTIC is the experience we had was as painless and non nerve breaking as you could ask for. The sales people are friendly and very knowledgeable and it is relaxing no high pressure to sell you anything just to get you into a car.
The one huge thing that Weymouth Auto Mall offers that no one else does is a warrentee on the power train no matter how many mile we put on the car, now that is a big WOW.
I would definitely recommend this pre-owned dealership to all my friends and anyone else that I might come across looking for a pre-owned vehicle.
