    Just bought a new Chevy SIlverado 2500 from DeCosky's. Experience was great, staff was great, visit was great. The team at DeCosky's is top notch and they gained a life long customer. I will continue to visit the dealership anytime I am looking for a new vehicle.

  • Great Buying Experience! Stress-Free and easy!

    I purchased a car from Bill Jones. Super nice guy and a very comfortable buying experience. Got a great deal on a gently used Porsche Boxster S.

    I found the exact SUV I was looking for and had to travel 3 hours to this dealership. I got the impression over the phone that I was dealing with a fair and honest organization. Unfortunately when I arrived at the dealership, the terms of the deal we agreed to over the phone had changed. The finance rate went up (even though I gave them all the info over the phone to get me approved) and the final monthly payment didn't included the taxes (even though I made it clear where I wanted my payments out the door including taxes). Unfortunately for me, I traveled far and really liked the vehicle but I should have had them put the plates back on my vehicle and left. Very disappointed in how this all went.

    We are very happy that you found the exact vehicle you wanted with us. Under no circumstance would we change an interest rate. The banks determine the interest rates based upon your qualification. As far as out-of-state taxes go, we always disclose what we can collect and what we cannot. Pennsylvania is a state that we cannot collect taxes for. We apologize for the confusion. We always try to make all info readily available to our customers.
