Can I pay cash for a car at a dealership?

A while back I bought a new car from a dealer with 1000 Sfr bills (I'm Swiss). I offered them a 1000 less than the price and when they hesitated, I picked up the cash and walked towards the door. The salesman called me back when I reached for the door handle. Cash is king!

I have yet to find a dealer that will NOT take cash.  They all take it because that is legal currency to trade with. (they won't make as much money off of you as they would had you financed the car but they CANNOT & will not refuse cash.

If you have enough cash to buy the vehicle, why on earth would you consider financing it? 

if you have the cash pay for the car and be done with it. they will take it as you have the car and must like it.

Sure you can pay cash. But don't fall for the "Yo-Yo" scam, it doesn't take three weeks to scare up financing. They want to drag you back in to the office to renegotiate less favorable terms (for you). Examine your situation and contracts carefully. Insist on getting the credit denial letter in writing, stating who is denying you and the reasons for the denial. And don't be so in love with the car that you will do something stupid to keep it.

Go to YOUR bank and get a loan,   sounds to me like they will come back with a loan for you,  that was "hard for them to arrange"  and it will be at a high interest rate.   

Knock $2000 of of the price they sold it to you for if you pay cash. It's already titled in your name so the value is much lower if they take it back to sell again and they will lose more then $2000. 

Yes, you can pay cash.  Do it now if you have the means, to avoid any unnecessary financing expense.

Cash will make the deal.  But if you have that much money available, why would you think about financing and paying all that extra interest ?    On the other hand, I do not understand "..they have not been able to open their bank...".  That sounds very strange, and not your problem.   I would check a little deeper before I handed over a pile of cash.  Something does not sound right.

Of course you can. However, new car dealers make far more money off financing new cars than selling them. They should be giving out financing like candy, not make excuses.
