You just graduate from tech school? You're name dropping like you know it all.
When I sold my cars, test drive, inspect what ever, gtfo. If someone wants to do what you're saying I'd tell them to get lost.
I don't get paid to work on my stuff. If my car is down for the day because my starter decided to shit the bed I don't get paid. So if it's a job I need to take a few days, what then. Say fuck it and lose 3 days pay? You're a fucking idiot.
I call the dealer, tell them there shit broke, come pick it up with a loaner car for me to use.
