Op was one one who approached the dealership about possibly getting the more expensive model- the dealership didn't solicit it....they wanted to correct the paperwork. It was OP's idea.
Everything isn't always a conspiracy in life...or in buying cars.
Per the OP, the dealership called the OP about the "mistake" initially, and they had a 90% bet that the customer would respond
exactly as they did.
This has absolutely nothing to do with "conspiracies." Has everything to do with the modus operandi for car dealerships going back decades about maximizing profit from
every aspect of a sale - some ethical, some not. The overwhelming probability IMHO is that this was
not a mistake, and the result was
exactly what the dealer wanted - they made more money.
Could the dealership have legitimately made a typographical error on the sales contract? Of course they
could. That's the dealership's out for "plausible deniability." Do I believe they did? No.
The OP provided no details/specifics about the make/model of vehicle(s) at issue, but keep in mind that a VIN isn't an arbitrary string of digits. Each chunk of digits represents a specific piece of information about a car; plant of manufacture, engine type, color, build sequence number, and so on. Swap two arbitrary digits in a typical VIN, and you likely won't end up with a
valid VIN number anymore - unless, perhaps, you transposed just the last two digits. That the "error" resulted in a
valid VIN that
just happened to be in their inventory just doesn't pass the sniff test.
No offense, but you simply will not convince me that this "mistake" just
happened to result in the dealership
having the car that
happened to match the VIN of the "mistake" they made, and that "resolving the situation" resulted in them selling
that very car to the same person
for more money.
Bankrate.com has an interesting story on this very issue
here.
Do me a favor. Go back and search Edmunds.com for the undercover article they did about six or seven years ago where they planted a salesman/reporter in various dealerships and learned about sales tactics they employ. Its a genuine eye-opener. Again, it isn't about "conspiracy theories." Its about consumers informing themselves with as much information as possible to get past any notion that car dealers are not there to be "friends," they're there to extract every possible penny from your pocket, from pointless "dealer prep fees" to extra eighth, quarter, half-point, or 12 months in financing.
As I said, however, this deal is done, the OP is happy, so there's no point in belaboring the issue here.
