Tell me what I should do

I'm currently working at both Carpets Plus and with my dad intstalling flooring. Last night I was hanging out in Appel Oil with my mom when she mentioned that Hansen Motors has a job opening for detailing cars. Since I'm going into into automotive, I figure that this would be a good start to get into the business. But I have two problems, one being my dad and the other being Steve Gunkel, my boss at Carpets Plus. I like working with both of them and I consider both of them my friends and I would hate having to stop working for them, but I'm not getting anywhere laying flooring and working in a carpet store when I'm trying to get into the automotive business. This could be my chance to get started working on cars, but I'm having a tough time leaving my dad and Steve. What would you do?
