Customer service was top notch. Filled out the finance application on a Wednesday evening. By Thursday late afternoon I was making plans to pick up my purchase. Easy to work with can’t imagine going anywhere else.

I don’t know Colin Choby. Marty was the Sales Representative we had contact with.

Terrible experience today. Drove over an hour just to get nonsense bait and switch and even though I made a solid offer they were way over market price on a beat up truck. I even brought a cashiers check. The way the math worked out they were over asking price! Manager couldn't even be bothered to come out and touch base. Pathetic. Looked like a classic nepotism problem. Cyrus was awesome!!!

Follow up to my daughter in laws review. Extremely disappointed with the lack of professionalism. I do not know if it was Tim Brenner's decision or Summit's policy, however, either way it's unacceptable. We test drove the vehicle when we arrived at 11:30 a.m. After the test drive we told the salesperson we would give him a down payment, knowing our son/daughter-in-law would be coming after work (4:30) to sign the papers and finalize the full purchase price which they had already been pre-approved for. Our salesperson consulted Tim numerous times and each time we were required ... Read More

Our salesperson consulted Tim numerous times and each time we were required for additional information, which appeared he was trying to buy time. After 4 hours I asked to speak with Tim directly. He stated there were now other interested parties. The sale is processed to whichever customer is the first to pay in full, our down payment meant nothing even though it was non-refundable. Tim stated this has happened a few times before (in his 34 years ) and it's unfortunate but not everyone will leave happy. Tim then asked if we would be interested in any other vehicle. We left the dealership at 3:30 p.m.. The other interested party did not arrive at the dealership until approximately 4:30 (per our salesperson) and we were notified approximately at 5:30 that the vehicle was sold. I've never had a business transaction where the business refused to take my money. I can only assume Tim either knew the other party or he is paid on a commission basis.

Unprofessional Management and Disregard for Customers-- My experience with Summit Automotive in Fond du Lac was incredibly disappointing, and the way the manager Tim handling this situation made it even worse. My husband and I were planning on purchasing a truck, and while we couldn't get to the dealership as quickly as they apparently wanted, my in-laws were already there working through the details on our behalf. Instead of communicating with us or allowing us the opportunity to finalize the deal, Tim came over, took the keys, and sold the truck to someone else. TOOK the keys off the ... Read More

Instead of communicating with us or allowing us the opportunity to finalize the deal, Tim came over, took the keys, and sold the truck to someone else. TOOK the keys off the table my in-laws were sitting at!! My family had already invested their time and effort into making this purchase happen, only to have the truck sold out from under us. What makes this situation particularly frustrating is that this wasn't a misunderstanding involving an uninformed salesperson. The decision game from a manager himself. When Tim spoke with my husband his response was essentially that half the customers are going to be upset. Seriously? That is your response as a manager? Rather than acknowledging the frustration or taking accountability, or even show a little empathy of the situation, he essentially dismissed our concerns as an unavoidable part of doing business. I understand that dealerships are in the business of selling vehicles. However, basic communication, professionalism, and respect for people's time should not be too much to expect. My in-laws took the trip (from Green Bay) and spent their time trying to facilitate the purchase, and the way this was handled made that effort completely wasted. They were there over 4 hours! Tim's response only reinforced the impression that Summit Automotive cares more about completing a transaction than building relationships with customers. Summit Automotive had an opportunity to earn our business and instead left us with a terrible impression. Based on this experience and management's response, I would not recommend this dealership, and my family will be taking our business elsewhere. There are plenty of dealerships out there. I would rather give my money to one that values its customers instead of treating their frustration as just another statistic. To our initial salesperson, Joshua, he should also be upset that he did not get credit for the sale of the truck.
