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.

Jeff Moran is a true sales consultant professional ! He listens to the buyer to find out their needs and wants. Being an advocate for the consumer is second nature for him. He treats people the way he would want to be treated. I highly recommend any vehicle buyer to reach out to Jeff......you will not be disappointed. :)
I have owned 3 yukons
I just purchased a 2024 Yukon Denali XL. This is my 3rd Yukon. So needless to say I am sold on this style of vehicle. The style and comfort are impeccable. Had a 2009, 2019 and now a 2024 XL. Never had any problems.

from the beginning of inquiring about the purchase of a new GMC sierra 1500 to the completion of driving one home from John Jonson GMC. This was the best car buying experience I have ever had over the course of 30 years. Both the sales team and financial team were outstanding, friendly, understood what I wanted without also applying any sales or financial pressure during my vehicle purchase. I highly recommend this dealership to anyone looking for a GMC and will be returning when needing another new GMC vehicle in the future. DL
Reliable and comfortable.
I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

On Haldeman Ford Lincoln at Lehigh Street the salespeople
On Haldeman Ford Lincoln at Lehigh Street the salespeople are professional specially Bill Bailey, he went above and beyond of his scope of work to make me happy when I bout my new F150. We went before Haldeman to another dealer and the salespeople their treat us very bad that is why we left and went to Haldeman Ford! I appreciate everyone there from Bill Bailey to the Financial manager for helping me to get my new truck, I will advise and recommend any person wants to get a great car deal go to Haldeman Ford Lincoln at Lehigh Street and see Bill Bailey.
I bought this truck new 8 years ago (and 77k miles).
I bought this truck new 8 years ago (and 77k miles). I use this truck for truck things like towing a 5,200lb trailer @8 times a year. The V6 has plenty of power and gets good mileage (22 mpg combined, 29 highway empty, 15 pulling the trailer). Reliability has been outstanding. The transmission needs a full flush about every 40k to keep it shifting smoothly. Other than that this truck has been without issue.

The sales person Luis was great and very helpful.
The sales person Luis was great and very helpful. Went out of his way to get the car delivered to me. He drove it 3.5 hrs so I can have it in time for a road trip. Also they managed to beat the best APR I got from a credit union. All in all it was a professional and positive experience.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Very smooth buying.
I’ve recently bought a 2023 Yukon from star. I made a appt with Colleen to see the car. When I got there I was greeted by her and then she introduced me to Kyle. He walked me right up to the car a had the appt on. Keys were even in his hand so I didn’t have to wait. I took it for a drive and fell in love with it. He knew the Yukon in and out. Then when it came to financing the car Justin in finance made it very easy. He gave me a couple options to make sure I was covered if I wanted. Out of every car I’ve ever bought (I’m almost 50) I’ve never been so relaxed start to finish with my purchase. I’ve even been back to ask questions on things I’ve forgot and never had to wait to get an answer. You can definitely tell this dealership is family owned . Way to go team. Thanks Star of Quakertown
