Absolutely. If a vehicle is discounted towards invoice, a salesperson can easily end up making $250 on a $100,000 fully loaded Audi A8.
Heck, I've sold used cars at asking price and still made $250 just because the dealership overpaid on the trade in.
All in all it all adds up and evens out, but mentally it can be frustrating coming into work on 4th of July and spending hours with someone trying to have fun looking at 4 cars and then leaving. And then finally selling one at 7pm and staying late, to make $250.
And with the way the pay plans are structured, it's hourly pay OR commission whichever is higher..so if you sold a few cars Wednesday Thursday for $2k, you can end up coming to work Friday Saturday Sunday, not selling anything, and technically didnt get paid anything more for those hours.
