It all makes sense. The average small 1-3 bay shop can't keep up with all the changes without a significant investment in equipment and highly skilled and qualified technicians. Therefore they pack it in.
If you can specialize and keep the bays full and become a guru in a certain area you will be more efficient and do well.
If you have a good marketing plan and offer convenience (open 7 days and late nights), have lower paid technicians, then you can do all the gravy work. (The chains)
If your the dealer your specializing, have marketing power and a good system.
If us small guys that are going to endure just be honest, build lasting relationships with our customers and a combination of things above we'll do alright.
Just my 2 cents
