Would a mechanic meet you to check out a used car?

I've heard that if you want to have a used car checked before purchasing, a good idea is to have a mechanic of your choice look it over. Could I call up a garage and ask if one of their mechanics would meet me at the used car place since I don't know any car mechanics? Also if I knew what car brand I was interested in, would a mechanic from, say a Honda dealership, come and inspect the used one I was interested in? I'm confused on where I would get a mechanic, especially since I ll be traveling out of town and possibly state to buy the car.

What does hook up actually mean?

I was at work today (a restaurant) and i was cashier and 3 people from Honda came in and i took there order and then i was in a joking manner like man you guys should give me a car and hes like oh yeah how come and i'm like because i'm still driving my moms (i'm 17 by the way) and he was like what's the car and i was like a pt cruiser and hes like oh man come on you can't do that to your self how about this you come down to the Honda dealer ship ask for (name) and ill hook you up it won't be the newest car but it'll be better and i was like for sure man thanks a lot and he got his food and said bye to everyone and i was see you soon and he gave me an okay sign with his hand then a thumbs up what does hook up actually mean and can a Honda dealership actually hook you up like don't they only have cars from like 2014 up so what does he mean?
