I recently used European Auto House to do a pre-purchase inspection for a 2014 Boxster that I was hoping to buy. I contacted Nathaniel who was very accommodating in setting up the inspection right away. He read my emails and responded to my questions right away. He was able to do the inspection the same day that I called. That afternoon he called me to discuss his findings. He very quickly figured out a number of things wrong with the car that I had no idea about. He was very knowledgeable and helpful. He gave me some very good advice about finding the right car for me. He saved me a lot of disappointment, headaches and money. I will call Nathaniel for the next inspection and I will certainly use him for service once I find my Porsche.

I bought my first Mazda from Tim on 9/2/2016. Ruth and I believe Ryan helped along the way and everyone provided great customer service. They went above and beyond to help me find and afford my 2015 Mazda CX-5. There was a minor issue I noticed with the appearance of the vehicle but they took care of it right away. This is by far the best vehicle I have owned so far and the best car buying experience I have ever had.

On 6/21/12, we purchased a used Cadillac STS from Brad Hayes, the owner of Hayes Family Auto in Watertown, WI. My husband drove the car to work the next day and it overheated. He had to drive home 50 miles in 90 degree heat with the heater blowing full-blast. We took the car back to Hayes and told Brad that if it was the head gasket, to repair it correctly (i.e. drill, tap, put studs in), which Brad agreed to do. Brad supplied a loaner minivan to use while the vehicle was being repaired. My husband's suspicions were confirmed; it was a problem with the head gasket. After a month of delays, excuses, vacations, and an inexperienced mechanic in this area of repair, Brad finally agreed to take the car to our family mechanic to have it reviewed. After 30 minutes, our mechanic determined that the minimal repair was completed by Brad's mechanic and that within four months the head gasket issue would reoccur. Our mechanic's suggestion was to return the car. My husband called Brad and after explaining the situation, Brad agreed to a full refund. On 7/24/12, after over one month of delays, aggravation, empty promises, and lies, Brad left the refund check with an employee instead of apologizing in person. We viewed this as extremely cowardly and poor business. We would NOT recommend this dealership to anyone. Buyer Beware!!!

Highly recommended. They fixed a major oil leak on my Mercedes-Benz for next to nothing. Incredibly fair prices and helpful, friendly customer service. I will definitely get service from Bernie's again.
