Case Studies – Our Service Solutions

A Collection of the Odd, Unusual and Interesting Found While Servicing our Client Vehicles.

Originally intended as a showcase for customers of our workshop and staff’s abilities, this page has evolved in an interesting and informative teaching tool, and one of the most popular pages on our site!

By nature, these are rather extreme examples of failures, and not what we typically find during service. Our goal at Atlantic Motorcar is to prevent these from happening to you and your car. But rest assured, if we can fix these challenges, regular maintenance is breeze!

We like to call this our “YES WE CAN!” page. You can also view many of these concerns on our Facebook page. Each photo can be enlarged by clicking on it.”

Now this is bad…whenever we find melted connectors, it’s what we call a “clue”, but also is a very interesting find, instructive even.
