The game playing has nothing to do with the make, but the dealer. That said, there are more ways for the Big Three dealers to play games as their makers have more cash-backs, different rates, and so on.
I've only used captive financing once, through MB Credit Canada, and it was a great experience. The dealer stepped aside and I delt directly with the financing company, and it was very easy and straightforward. I would be hesitant to trust the dealer if they were acting as a go-between. One MB dealer stated that MB Credit was difficult and they would finance me through a different firm. Smelled bad, that did. In the end, I filled out a half page credit app, faxed it in, and within 15 minutes they called me back approved. Did it from home, actually. Easy as pie. The first dealer was obviously up to something where they could make more on some different financing.
The last few cars we've bought were cash purchases, and most dealers looked pretty sad when they found out we weren't financing. I suspect that a great deal of their profit margin can come from the financing.
We've got a couple shady-esque things on the go around here lately. The classic "with $3000 trade" fine print to explain the great price is aggravating. The new-ish "sold pending approval" scam is dangerous and legal, meaning people get snared and can't get out. I have heard many dealers now practically refusing to talk price with financing customers and with loans now going 84 months or more, using all kinds of tactics to sell the payment. Again, contracts get signed and legal recourse is difficult.
Another one I've heard is life insurance on the loan, and it's another "pending approval" deal. A friend of mine got caught in this one and ended up costing him about $1500 he hadn't planned on spending. Kentwood Ford, surprise.
And those "bi-weekly" payments! Ha! I can't imagine myself at a dealer that did that. I would just laugh myself silly as I drove away. City Ford here advertising super low payments based on a reduced payment for the first few months of the term. Of course, you pay for it in increased interest, but they don't explain that in the ad. "Windstar's for only $49 a month" is how they execute that. Of course, after six months it goes to $500 a month, but don't worry, in six months you'll have won the lotto, right?
Forest Gump: Stupid is as stupid does.
That line could have been penned solely to describe the game played between dealers and "ups."
