Not necessarily. The Computerized Vehicle Inspection System is just required in case you are going to inspect vehicles from the group 1a.
Regarding opening a body shop or repair shop, what are the first steps to registration?
You can start by consulting the DMV Commissioner's Motor Vehicle Repair & Body Shop Regulations, and you can download and read the Repair & Body Shop business requirements
good to know, do you know someone who has recently registered a body shop and auto repair shop? can I get information online?
