It was changed a while back to that scenario but more recently they changed it back so now any perks taken don’t reset. That goes for selling a car or not selling and reclaiming back to garage. The perks are still taken in either situation.
Not sure why they had it set to not resetting, as was the case in all other versions of FH, then changed it to resetting only to rechange it back to the original. It was fine either way. When resetting was there, you could at least get more XP, CR, etc. on an unsold car but it cost you to do so. Now you don’t, so don’t have to waste mastery points on an unsold car. Makes no odds either way.
