Used GMC Sierra 2500 Denali for sale near Exeter, PA

Caleb did a good job of helping us when we were buying a used car here. I was impressed at the walk around the vehicle where he pointed out any dings or scratches he noticed to make sure I was informed.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Bought a few cars from this dealership. Great customer service and the staff is always friendly.

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Quick and great service while keeping you updated on the work performed on your vehicle .

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

Easiest car buying experience. Wouldn’t dream of going anywhere else. Thanks to everyone involved!

I came in for a state inspection and had the 15,000 mile service done and it was done quickly and done while I waited

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

The team at Star is absolutely amazing! My family has bought multiple cars from them and every time we are treated with the upmost professionalism. The deals are always extremely fair especially with the lifetime warranty that is given.

Great Staff and Great Product! Only place I go for sales and service! Highly Recommended!

Hands down the best buying experience either my wife or I have had. Robert, Josh, Joseph and Mark were great to work with. No haggle pricing allowed us to speak openly on features, pros, cons and needs of our family. My trade-in value was higher than average KBB and what I had hoped for based on condition. The whole family took part in purchase, ensuring our 2 year old would like the new truck! From hoisting our son and NB car seat in and out of trucks, to arranging for change of address forms, to reading the vehicle for pick-up, the experience was easy, efficient, and fun! This is what purchasing a vehicle should be. We’ll be back next year for our family’s SUV…

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Honest and very transparent. Everything was explained in detail and the staff was very friendly. Highly recommend Star for all your truck needs.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Honest, straightforward and smooth process. No hidden fees, no haggling, reasonable fair pricing. Zach was awesome to work with, best salesman I’ve had.

good service , friendly, very polite . they changed oil and rotated tires in a timely manner. I will recommend to others KEIM CHEVY to others.

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

I can't say enough here. First of all, Jordan Good should change his name to Jordan Great. Not to diminish anyone else who I saw, spoke to, or dealt with there, but Jordan was a pleasure to work with. I'm not sure he would say the same about me, though. I've been doing my homework and had many questions. All of them were answered quickly, clearly, and honestly. Today was my 6th visit to a dealership since Thanksgiving, and will likely be the last visit for me for quite some time, since I was able to get exactly what I was looking for(actually more than I was looking for). I love the no-haggle approach. I also never felt any pressure, which I assume is because these guys know that they are going to sell the vehicles on their lot, so they don't have to be abrasive about it. I drove a little under 3 hours to buy a truck from these guys and it was worth every second. I guess the best way I can describe how I feel about Mark Martin Motors is that I just purchased a pre-owned vehicle from these guys without even taking it for a test drive. I figured I had 150 or so miles to test it out on the way home. It passed the test folks!!!!!

We had a wonderful experience with Jordan @ Mark Martin. As an out of state buyer I was bit apprehensive but Jordan worked with us at every level and was very helpful in answering questions as well as timely communication back and forth. The vehicle was delivered last week and was in great shape, matching the description and images on the MM site and cars.com. We ended up using Lemon Squad to go through the vehicle and provide a report on the vehicle. No major findings and felt even more comfortable we were getting a good vehicle. Thank you again to the team at Mark Martin and especially Jordan!

Great truck dealer! They are giving me a solid price for my trade. They have great deals on a large selection of inventory! My deal is pending only due to the Coronavirus. Thanks a lot Zach!

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Today I found a truck I've been looking for, last couple weeks. The buying of a new vehicle experience can really show you the worst of sales practices and environments. For instance - you call ahead for test drive--you drive 50 mins. - You take it out-the vehicle has 7 miles of fuel-yes 7 miles till empty-- a serious whining noise when moving- Nope let's go home. Well today all that changed. I found a truck on internet like I wanted-called this morning to see if it's still in stock. It was-- got there about 11;30. The truck looked like the pictures on the web. Took it for a test drive -more than half a tank of fuel. While i was gone they were appraising my truck. I was ready to fight for a amount--got back--they offered $4000 more than I had in my mind-NO NEED TO FIGHT! Their sales area was so relaxing to be seated in. Nicely decorated -polite leisurely dressed sales folks- no fancy suited faces that have to smile at you. Just welcome to my house --let's get this done! They got me a interest rate lower than I had in mind-again no need to fight! After all paper work was complete--I was ready to move to the office with the fancy lighted signing table where you write with your finger on the glass. Nope, didn't happen. He put a paper on the desk -told us what we were signing and where to sign--YES we used a pen to sign these documents. WOOOO! All done - we clean out my trade in --hop in my new (to me) vehicle and headed home. Smiling and happy. In and out of a car trade and buy in 2 HOURS--yes 2 HOURS. The guys we dealt with were Caleb and Jordan-great -pleasant- informed-no pressure-get this done experience. While loading my truck a guy in shorts --a pull over shirt and a baseball cap came out to thank us for our business and wished us a safe trip home--I believe he was the owner. This happened at Mark Martins Motors in Manheim, PA --Sorry I had a share something GOOD happening in this world today. 5 stars out of 5 -- Thanks for listening--Sam

As ALWAYS VERY CURTIOUS AND PROFESSIONAL FROM THE MOMENT i WALK THROUGH THE DOOR. The facility is well maintained and the staff is very interested in serving my needs as a customer.
