CarMax sells 1 million vehicles a year between wholesale and retail. CarMax has the largest wholesale auction in the USA. Yes, larger then Mannheim. CarMax has appraisers in place to handle the volume, and the freight partners and system to move the cars. CarMax has the funding in place to handle what ever agreement is in place to pay on site for vehicles and bill VW if needed. There is no better partner to help facilitate the shear number of vehicles that will driving to dealers once the doors have opened for business.
If you think VW alone can handle this I believe you are mistaken. Research the volume of business created by cash for clunkers and realize that was distributed among thousands of dealers.
And VW has little to gain by using them and a LOT to lose by using carmax for this. It would totally piss off the VW dealer network, at a time when relations are pretty fragile. VW would have to PAY even more to carmax to handle the situation, their dealer network could handle the job cheaper and maintain more control over the process.
If VW is stupid and foolish enough to give people money for their tdis, and let them stroll into carmax to turn in their car with a pocket full of money, when they are needing another car, they really don't deserve to be in business where profit is of a concern.
It's already been established that the buy back will be a lengthy process up to two years. I think that gives VW plenty of time to handle the situation.
And contrary to your opinion, i think VW is not at that much of a disadvantage to carmax in doing this. Their dealers have a 4:1 advantage in numbers, and they aren't totally new to valuing used cars, etc.
I see the logic in what you say, but there is no way VW gives carmax first shot at vw buy back money.... None.
VW may use their services for transportation, etc. but they will want back as much of the market share as they can get and know they will get very little if customer turn their cars in at any place except a VW dealer, regardless of how efficient another company can accomplish all this.
My guess is that since they have a couple years to do this, vw will take certain years of cars in at certain times, or plan it out in some other fashion similar. Nobody knows at this point but there are aspects that are known through common business sense, and one of those is you don't send you customer to another dealer with a pocket full of money you just handed over.
