I purchased a 2024 Jeep Wrangler Willys 4xe from Blade.
I purchased a 2024 Jeep Wrangler Willys 4xe from Blade. Ian Hower was very professional, courteous and helpful. Juan the Sales Manager was also very professional. I purchased the vehicle for a fair price, and they eventually came up to a reasonable trade-in value. It was a long process, but the outcome was worth it, for me.
Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

I bought the vehicle online without ever seeing it in
I bought the vehicle online without ever seeing it in person. Easy transaction. Great financing and smooth delivery!
Great luxury ride with great pulling capabilities.
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

Service was great!
Service was great! I made an appointment with Ashley for 10am but life was lifing so she rescheduled me 3x that day with no attitude and finally made it in around 3:30pm. Then I was helped by Marquell. Cool guy! He gave me a price I couldn’t afford at first so I was about to leave. He stopped me and said “Let me speak to my manager” they talked it over and gave me a price I couldn’t refuse! I really wanted a Dodge Challenger especially because Dodge aren’t making anymore high horsepower/gas powered vehicles in the Charger/Challenger line. I walked out very satisfied. Mission accomplished and a dream come true!
Really impressed with the performance
Nicest truck I have ever owned preforms great with my RV Truck is comfortable and still works great when you need it to preform. Ride is nice and very roomy for all that want to travel with me

Sean and Jackson were awesome.
Sean and Jackson were awesome. Most honest and straightforward team that I have dealt with all my years leasing cars. In my case they went above and beyond expectations, even to the point of providing a greater discount than what was agreed upon because of an incentive issue. I would not hesitate to contact them if you are considering a new vehicle!

Really great experience with John Kerry and his
Really great experience with John Kerry and his #LuckyBuyersClub at Seelye Auto Group. John was knowledgeable, helped us find a vehicle within our budget that met our needs, and was an absolute pleasure to work with. He wasn't pushy, and he brought up options that we'd missed while reviewing the online inventory. The whole team was great at this location, and I highly recommend Seelye Auto Group. Definitely ask for John!
