If they do decide to put more money towards Carmax (and I really hope they do not), it better at thevery least get them majority control of the company.
I think they can get up to 63% ownership of Carmax if they buy their options. I would imagine that will happen eventually when these other matters are resolved, i.e., SC is sold or VD is 'monetized.'
There appears to be some confusion over using the PAC for Carmax though. I don't believe those credits are transferable and we don't need them for CUU. (If credits were transferable, then they would be worth cash and we could sell them to some other outfit that needed to extend their claims, couldn't we?)
I think the PAC argument is a non-starter, unfortunately. But, I will do some digging to see if there is any possibility--never say never.
