In the UK but have another data point - was looking to buy a demo car from a VW dealership - paid the deposit and it was a decent amount under MSRP as it had 1500 miles on it. Phoned up the next day to say another dealer in their network had already sold it earlier in the day but not uploaded the paperwork yet. Polite, but firm, email was sent back opining being disappointed in their customer service as the dealership was so close to work and would have loved to have a long-term relationship with them yielded - a 1250 GBP discount on ordering a new car, as specced, at MSRP. There are good dealerships out there, but it's liking finding a diamond in the rough.
