Bundle,home,auto,business and form a Corperation or Limited Liability Company.BGR is not a part of Bob George Ent.LLC.When we switched insurance companys a few years back the agent visited our shop and documented our business.Our race cars are insured by a speciality classic and race car insurer seperate from our business,our business supplies parts and service to motor sports partisipants with a strict customer policy.The problem with trying to incorprate racing as part of the business structure crates a liability that no insurer will want to touch.Business is business,racing is a hobby.A machine shop or any garage type business should not involve racing,however it can be deducted as advertizement.
