I am close to buying an inexpensive used car. I have work permit so allowed to put in my name but 3 hours in immigration and day wait for Certificate of Residence is a hassle and 1900b.  
 

alternative is to put in my company. Anyone who has put in company would love to hear pros and cons vs in my name.  I will occasionally rent the car out. 
thx

Do you have a license for a rental service?

 

Thailand Foreign Business License: Rental Services (siam-legal.com)

A work permit is not a requirement for registering a car in your name.

 

Considering the potential for getting embroiled in legal disputes between yourself and the renter and potentially getting sued by a third party as owner of the vehicle for damages caused while the vehicle is being rented out, in my opinion you need to have your head examined for even considering doing this.
