Car maintenance is a recurring, necessary expense that no one wants. However, by maintaining your vehicle, a driver ensures prolonged auto life and prevents further more expensive repairs. With parts and repairs costing more due to supply chain issues, finding a shop that you can trust is important. 

Specific auto service centers help keep your vehicle functional with preventative attention. These auto service and repair companies have operated on US soil for several decades, ensuring quality care for your beloved car. 

Auto Repair History 

how many auto repair shops are thereAfter Henry Ford popularized the Model T at the turn of the last century, early auto dealers began peddling their services out of existing garages, fixing cars in the same facilities where they were sold. From 1900-1930, American automobile businesses were built by tinkerers and visionaries. Then, during the Great Depression, used cars rose in popularity, with dealerships surviving financial ruination by capitalizing on their parts and service departments. Thus, the automotive repair industry was born.

In the post-World War II years, the auto repair industry saw a boom in auto repair shops that were not associated with dealerships or manufacturers. Many of the mechanics in these shops were WWII soldiers who learned their craft courtesy of Uncle Sam during their years of service. And, as the economy grew in the 1950s, Americans were buying more cars than ever. As a result, the auto repair business was booming.

Today, there are over 234,000 auto repair and car maintenance shops in the USA and nearly 800,000 auto repair technicians and mechanics. Here are the Top 12 Largest Auto Repair Companies:
