Amber kept me updated on the progress of the repairs on my truck. Friendly staff. Very nice loaner vehicle to drive while mine was in for repairs.
Truck is a Solid vehicle overall.
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

I had a great experience buying from out of state.
I had a great experience buying from out of state. I would do business again and would recommend to friends and family. Here's my experience: I found a 2024 Jeep Wrangler 4xe which included my wish list options including the active safety group (hard to find). The price seemed good compared to what I see in my area (UT). I reached out to sales at Bill Luke and asked for the "out the door" price. They came back and the only additional cost was window tint (as mentioned in the fine print on cars.com). Aside from that there was only tax and dealer fee. They took additional pictures and sent me a video tour of the vehicle. I signed a deal with the finance group, who did their best to match a loan rate from my local credit union. Shipping seemed reasonable, but I decided to pick up in person (they were even open Sunday which made things flexible for a weekend trip). I booked a flight and showed up just waiting for someone to try and tell me there were additional costs, but they were true to their word on "No hidden fees". We tested and inspected the vehicle, then shook hands and drove away. The staff were very friendly and kind. Thanks Nabeel and Justin in sales, and Brian in Finance!! 😀🤜🤛 ⭐⭐⭐⭐⭐
Love it.
I love the new features this truck offers. I would highly recommend this truck if your looking for a Diesel. I provides all the features and benefits you would want.

Everything went perfectly.
Everything went perfectly. From arrival to departure. I ordered a new Key FOB from the Parts Department, they called when it had arrived, made a WEB appointment, all very easy. I was greeted promptly and taken care of by very friendly people. When the job was done, I was helped to use my reward paints toward payment. The job was completed much faster than I had expected.

Rocky was very attentive to my concerns and explained everything with me thoroughly regarding future service. However with the oil change service they should wash your car. They provide that service at other dealerships.

Best service in Indiana!
Best service in Indiana! My car decided not to start, yesterday. Called Alsop Chevrolet in Attica, this morning. They came, picked it up and took it to the shop and installed a new battery for us, then delivered the car back home for us! No one else would ever do that. Thanks, Tianna for getting us back on the road! Glad we have great service available to us older folks! Thank you Mike for a great team over there! Much appreciated! Ron & Becky Bradford

Joe was awesome about taking and sending videos of the brand new Grand Wagoneer that they got on the lot before photos were even available online. We stayed in close correspondence and in less than a week, we called the new vehicle "ours." We had a. great experience with Joe and the team at Russ Darrow West Bend.
