Don't give up. ONe way to get the right information is to do a search on ebay for "white rotary" and read the information about the machine that matches yours. Then use that information, like model number, to do a search on how to oil the machine. That's what makes it run slowly. And yes, you can use a white rotary to sew car seats. I got my son one at a yard sale, and he sews heavy webbing for diving equipment. (heavy needle and thread) IT might be a good idea to find someone who sews...granny type....to give you a lesson or two, but YOU CAN DO IT!
