It's not unheard of for dealerships to pull credit prior to placing an order. It all depends on what you're trying to order and where from. If you go to Miami and put an order in for a Hellcat, they won't care even if you look like a bum with 1 shoe on. They'll be able to sell that car in that market. But, if you're in the Midwest a bit removed from a major urban area, if you try to order something that is too much car for their local market, you might get hit with a credit check.
When I was a new car sales manager back in the late 2000s, I had a guy come in who looked a lot like a very new Army soldier. Young, high and tight, dressed like a knob (tight jeans, tucked in tee-shirt with rolled sleeves... basically the very epitome of someone who just got out of basic and was scared to walk around in public with their gig line being crooked). He was inquiring about a 2009 GT500. He talked to a salesman and wanted to put an order in. We had allocations for 2. I asked the salesman to inquire how long he had been in the military for. He came back and said 1 year. I then instructed the salesman to go over the pricing and explain what the ballpark payments would be to make sure he was OK with it. Of course, the guy said yes to a $1,200/mo payment. Being a recently separated military guy myself, I knew that the guy couldn't have been making more than $1,800/mo at the time. So, I told him in honor of his service, we wouldn't charge him an ADM or a deposit, so long as he passed a credit check. His credit came back in the LOW 500s.
I ended up selling him a used Misubishi Eclipse

. He put something like 10 grand down on the 12k car.
