This definetly needs to be patched, but it's still funny! I was driving one of my reskins, one of the AC44, and when I quit out, I got this achievement.
Probably because they combine the stats of Sand Patch Grade and Cane Creek AC4400 in the player profile area? A similar thing happens with the GP38 in Peninsula Corridor unlocking the Northeast Corridor GP38 miles achievement (TSW2020). SD40 from SPG unlocks the achievements also this way. Same behaviour on Xbox. However, SD40 on CRR is separate.
