This was my second time coming to Lombardi for buying a used vehicle. Nick Ruzon was more than helpful as always when it came to choosing the car that was right for me. I highly recommend any who is looking to buy to stop at Lombardi in Wilmington. I will next time I need a new car.

Dave and the rest of the staff were amazing.
Dave and the rest of the staff were amazing. When I first came in, my intention was solely to look at a bunch of different dealers and see what I liked. Even with just looking, Dave gave me the same attention as if I were buying that day without being too pushy to buy. He asked me what I liked and showed me a few options, took me for a test drive and informed me of the pricing. After looking around at other dealers, the car from Arnie Bauer was the best option and fit for me. However, it wasn?t just the car, was Dave?s amazing customer service. Other dealers once they heard I was only looking, weren?t interested in really helping with the same enthusiasm as if I were set to buy. Dave made the loookinf and purchasing process smooth, helped ensure great pricing and just overall made my first new car buying experience amazing and one I won?t forget. 100/10 experience

I had major work done on my car and I couldn?
I had major work done on my car and I couldn?t be happier with the turnout. I had my transmission replaced along with a couple other issues on my 2017 vehicle. It took a while for the entire thing to get completed, but I was given status updates throughout the process. I picked up my vehicle late last night (5:45 pm). I was surprised the service manager was still there and he took the time to go over everything that had been done to my vehicle. The total price was slightly lower than what I was I was told it would be at the start. I was very happy and wasn?t expecting that. My car is driving great today and so far I?m extremely happy with the result from my service experience. I?m very appreciative of the help I was given and the customer service I received. Thank you Justin and everyone who worked on my car. ?

Great purchase experience
The Team that my husband and I worked with Dillon, Tim & Dan, were all very helpful and courteous. We had a certain price point and they managed to get us very close to where we needed to be AND we got the car we really wanted. Buying process was seamless, communication was great, and customer service was wonderful. This was our second purchase with Haggerty and we highly recommend!! Thank you
