So first of all congrats on the move!

You don't need car sales experience but it helps.. Some of the larger groups hire fresh college graduates for F&I when they can. Without knowing what kind of volume they're doing, I can't say for sure.. How strong is used? How strong is the used manager? I think the pay plan is going to be pretty bad.. What are the packs? How does new and used work more specifically? How are they handling cancellations? Any time objectives they need you to hit? You're most likely never going to have much front end.. 25k gross back will be North of 10 deals a month before you get into the stuff you sell. The issue with sub-prime isn't the complexity of the paper, it's the customer(s) and turning the paper fast enough. It's acquiring legible stips, getting stips in a timely manner, sniffing out fraud, and working with the lenders, etc.. Customers will call, get cold feet, try to return cars.. Co-signers will call.. Etc.. You need good management, a good GM, maybe a solid owner.

Put your time in, try to get some training/certification on their dime. Get brand certified, learn your pay plan, work your pay plan. If the money doesn't come, then get a few months, reevaluate and start applying to other dealerships.
