As a Droman parts supplier it’s very interesting to read this article by John Mylant . The artcle published in Seeking Alpha  describes Dorman as being "The company that services the automotive aftermarket with replacement parts and fasteners for automobiles and heavy-duty trucks. With about 133,000 items that they designed and engineered themselves, they dominate the automotive aftermarket. 90% of the revenue is generated from North America (United States and Canada)."

It would seem obvious that with the recent recession and high unemployment has an influence on the automotive market. Vehicle owners are more likely to keep their current vehicles longer, performing the necessary repairs and maintenance to keep them running and well-maintained. 

Therefore finding good quality replacement parts to keep that slightly older car on the road is becoming more important to the vehicle owner. Dorman by designing and manufacturing it’s own aftermarket parts has risen to the consumers need by being able to make and produce quality auto parts at very competitive prices, as an aftermarket auto parts supplier we have always been delighted to sell Dorman parts.
