New Tahoe Purchase
Excellent Buying experience from order process to delivery.. Salesman Bo Setlock was wonderful..
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Great place!!!
After not having the greatest luck with car dealerships, I decided to try once more. Eli immediately made the buying experience super easy and stress free. From the start he was honest and got me into exactly what I wanted. In the span of a few days u was driving home in the very car I went there for. Eli was very pleasant and wholesome. I would recommend him to anyone!!
I love my Acadia Denali.

Absolutely Amazing Service!
The purchasing process was beyond simple and everyone working there was beyond kind, we where unsure of what kind of vehicle we wanted (Mustang or a truck) so we test drove a lot. No problems with them what's so over, bought a truck, was in and out of there in 30 minutes, I heavily recommend them :)
Best family hauler on the planet
I bought our 2007 Yukon XL Denali in 2018 when it was 11 years old. I bought it with 192,000 miles as a 2nd vehicle, and it now has 242,000 miles and is our primary traveling vehicle. It is by far the best family vehicle I have ever owned. I did some maintenance to it when I first bought it, such as front suspension work and a few other things, but it has been absolutely reliable and has never let us down in thousands of miles of road trips. We have two kids, and often take trips with our in-laws, so all six of us fit in comfort plus the dog. Best of all, when it does need maintenance, everyone and their sister knows how to work on it, and parts are cheap and widely available.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Newest & Biggest SUV I've ever owned
The styling looks great outside & everything functions as it should. It has loads of options, heated & cooled seats & steering wheel, very cold air, big comfy 7 seats. While not a luxury-looking plush interior, it is very nice. A couple pieces of plastic molding inside are loose, a back panel I tried to take off & the visor mirror on drivers side. I've owned this for 6 months & adore it! Very roomy.

My husband and I drove 5 hours from Erie, PA to Heritage
My husband and I drove 5 hours from Erie, PA to Heritage CDJR Harrisburg to buy a vehicle specifically from Sidney Ruth! Mr. Ruth was extremely helpful in our search to purchase a Jeep Wrangler Sahara. My husband found a Sahara on-line from Heritage and Mr. Ruth immediately reached out to us and was so helpful to us!! Mr. Ruth sent us a very detailed video about the Sahara and from being out of town it made us feel much more comfortable in making the drive to Harrisburg to purchase the Sahara. From meeting Mr. Ruth at Heritage he was extremely kind, helpful, informative, and made everything to be such an easy and smooth process!! To complete the deal we had a couple of small issues including obtaining a Freedom Panel Bag and some touch up paint and Mr. Ruth took care of everything immediately and that sealed our deal and we are extremely excited customers and we owe all of our thanks to Heritage's superior staff Mr. Sidney Ruth!! Thank you so very much Mr. Ruth for everything!! We are so excited to drive home in our Sahara thanks to you!!

2024 GMC 3500HD AT4
This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

Nice easy presses from start to finish.
Nice easy presses from start to finish. Sales team was a pleasure to work with and happy so far with my experience with the dealer. Shout out to my salesman Jeffrey Matthews for making it low stress buying a truck from them.
Bought 7 over the past 21 years!
On my 7th one. That should say it all. Quality crafted, full of great features, super smooth ride and plenty of room for up to 8 people plus a ton of gear.

Pre-Owned Vehicle Purchase
I had been looking for a pre-owned car online for some time. Found a car at Frederick I was interested in getting more information about a possible purchase. Cody was very helpful when I arrived at the dealership. Cody was very helpful getting the information that I needed to make the decision. I really appreciated the straightforward process. I was able to purchase and drive the vehicle home the same evening.
