Awww… RIP formerly green Accord. Will you be changing the color of your avatar to your new car’s color?
I used to work for Volkswagen and Mercedes dealers, and they swap cars to get the one a particular customer wants. I even had the dealer my ex was working for do a swap so I could get my 1995 Golf in Dusty Mauve (I loved that car: first clutch replacement at 190K miles, she made it over 225K when I broke up with the bf that I had given it to).
For popular models, especially if you’re being particular about color and trim features, there usually isn’t much negotiation on price, so consider yourself fortunate that you were able to negotiate what you feel is a reasonable price. Back in the ‘80s, it was a real pain to try to track down who had what inventory, but the internet has made that easier. Still, realize that your dealer will have to incur the cost of sending someone to make the swap – sometimes they drive a hundred miles or more, if that’s where the nearest car that meets your specifications can be found, so they’re making even less on this deal. My son works for an Audi dealer, and when he was a driver, they sent him on some trips that were more than 140 miles away.
When I bought my 2008 Mini Cooper S (RIP; I really loved that car) there was no negotiating on price because there were very few dealers at the time, but the demand for the car was picking up. Plus, they built my car to order in England, so I had to wait for it to be manufactured and shipped. What we negotiated on were the little extras, like mud flaps and such. At that time, Mini was doing nowhere near the volume they’re doing today, which is still far less that what Honda produces, so the larger makes don’t build to order like that.
We had a similar experience with our 2011 VW Jetta TDI – they were in very high demand because they had redesigned the diesel engines to new specification. We went to the dealer just to test drive and check it out, but we decided not to be picky about color and bought the last one they had on the lot. They were in very high demand at the time, and people were on waiting lists for some colors, but no one seemed to want white.
As others have noted, you will get your car. You have not been duped out of your deposit. New car dealers are especially well-regulated and organized, since they have to live up to the standards set by the manufacturers in order to uphold that reputation.
