It’s been great (so far) dealing with these honest, engaging, personable people of HALLADAY Motors. They dealt factually and honestly in arriving at a fair price for a used car I was interested in. They gave up some-I gave up some - and the result is satisfaction for both parties.

The purchase experience at Halladay is as good as it gets. Shawan efficiently explains all the post-purchase options, but is not pushy. This is just as it should be.

The staff members were professional and the repairs were done correctly the first time. I would recommend Halladay Motors to anyone.

Halladay dealership was easy to work with from test drive to purchase. A few issues (ie. additional key and seat repair) need to be worked out. I am confident they will stand behind there word to resolve these issues.
