I have no clue what crazy things people think. If im buying a new car, Im buying a new car. If your leasing a GM vehicle, you can still turn it in for another GM vehicle. BK wont stop the business, for one second. Uncertainty should be in the main markets(up still) and with GM stock(down.) As for its effect on Sirius(minimal to none, and their are scenarios were it would actually benefit Sirius, we just dont know how(increase in other brands, or reworking of GM XM contract). So selling on this news is a bad idea long term, but may work out for you short term. Long term with sirius stock is around 4 days.
