I’ve leased or bought 4 vehicles from Robert Basil over
I’ve leased or bought 4 vehicles from Robert Basil over the last 10 years. Madison has sold me my last 2. She’s been great. Very helpful. Always willing to find the answers to your questions. I especially like the “engine for life” warranty on used vehicles. It has come in handy a few times.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

My experience was very good.
My experience was very good. Gavin was a good salesperson. However, I would NEVER EVER recommend a salesperson to tell ANY customer to put down $14,000 which was incredibly obscene for a down payment on a 3 year lease. You should NEVER be that hungry for a commission. My favorite salesperson that I knew for 35 years at West Herr East Aurora would never recommend that to me. That is the trust you build with your salesperson-customer relationship. If I had to do this all over again--I definitely would NOT. It was too late to back out of this deal. Basil is known for great deals, and this was definitely NOT a great deal no matter how you spin it. I was under much pressure myself to get a new car due to previous lease expiring, tariffs coming into the mix soon and my mom having cancer with only a few months to live. But, this scenario will never happen again, I will make sure of that.

I had a great experience at Basil Resale Sheridan.
I had a great experience at Basil Resale Sheridan. Ray Baller gave me a very good deal on a Honda Accord, everything went smoothly, and he was very efficient during the entire process. He was also very polite and respectful throughout our interaction. Just look for the guy with the big smile and he will take good care of you.

I recently purchased a brand new Silverado from
I recently purchased a brand new Silverado from Cappellino Chevy and the experience from start to finish was absolutely seamless. Every step of the way was smooth and efficient, exactly how buying a vehicle should be. What truly sets this dealership apart is the personalized service I consistently receive, especially from Caren Stevens. She goes above and beyond to tailor the experience to my needs, making me feel like more than just another customer. Her knowledge, professionalism, and genuine care always ensure I walk away feeling confident and satisfied with my purchase. If you’re looking for a top-tier, buying experience, I highly recommend working with Caren and the team here. They make the process easy, enjoyable, and personal, every single time.
