Joe Martin and his team make buying a car incredibly easy. They are customer-oriented, listen to every need, and just do an amazing job of satisfying those needs. They are polite, thorough, fair in pricing and trades, and just completely professional! I will ALWAYS buy from Unique Ford --- their commitment to their customers AND the community make it easy to recommend them.

Matt at Tim's truck capital was awesome to work with. He answered all my questions and was willing to work with me being an out of state purchase. I found a truck in state instead, but I'd definitely work with Matt again if I need another work truck. Great business with a great selection of trucks

Radley Cadillac review
I had a GREAT experience with Penny and Radley Cadillac in Fredericksburg, Va. Penny had helped me look at another vehicle earlier in my car buying process and I was ecstatic when the car I ended up buying was at Radley. Penny made my car buying experience very comfortable. Not once did Penny or Radley Cadillac make me feel pressured or uncomfortable during my buying experience. They really acted like a friend lending support. I would highly reccomend Penny Lloyd and Radley Cadillac.

CarMax Mechanicsburg review
Love the personality of the reps and they are always eager to help! They don't push you into buying more than your original budget and won't bother you about it! They also will let u browse the lot on you own, and all there cars are unlocked! I absolutely love there transfer program where they will transfer vehicles to your local stores without an obligation, and many transfers are free! Only complaint about Carmax is that I feel the cars are a bit overpriced, but it's worth it in the end for there customer service!

Jen Lilly of Canobie Lake Toyota made things easy and was receptive and accommodating to my financial concerns. She presented me with the best options and managed to get me off the lot with a new vehicle within the confines of what I was comfortable with financially. Highly recommend seeking her out if on the market for a new vehicle.

Colonial Chevrolet review
I recently purchased my 2026 Chevy Traverse from Colonial Chevy in Acton, and I couldn?t be happier with the experience! From start to finish, the team made everything easy and smooth. Matt was my salesman, and he went above and beyond to help me get the Traverse I wanted, even though they didn?t have it in stock. From Matt to the GM to the finance team, everyone was professional, friendly, and efficient. The process was quick. I wasn?t stuck at the dealership for hours like you often are when buying a car. Since my purchase, I?ve reached out to Matt a few times with questions, and he always answers his phone right away, which I truly appreciate. I would absolutely recommend Colonial Chevy to anyone looking for a great car-buying experience!
