Basically, v1.02 is what v1.01 should have been in terms of the direction purchased vehicles can/should be taken. I do not believe this resolves the issue of vehicles that you have already purchased and are already in your garage though, as it should not anyway. There is no way PD/Sony would be able to recognize how vehicles were purchased. There is no way for them to discern whether the vehicles you have in your garage were purchased via glitch, grinding or store purchased credits. And thus, if you have a stockpile of vehicles in a v1.00 save game, you are free to update to v1.02 and sell them there. This worries me though. Be very wary about continually selling these vehicles for exorbitant amounts of money as PD/Sony may be able to track your spending habits via credits purchased in store versus credits earned versus credits used for purchases, etc.
