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.

DealerRater Oct 16, 2023

Great experience! Garrett did a great job, supported by management and finance. We love the truck!

Entire staff was extremely helpful and professional. Special thank you to Vicki Holmstedt for her assistance.

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.

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.

Cam Swedburg should be commended. The vehicle repairs were completed as promised. Dealership provided a courtesy wash as well as a military discount for my service. This vehicle had to be towed in for these repairs so my confidence has been restored. Thanks Halladay Motors!!!
