Just quickly checked with one of my contact here who is involved in that second-hand car trade industry.
The "ONLY ONE" in the states who is offering similar tactics is
Manheim. My contact here is also telling me that this company already worth/quoted by investors @ 10billions USD.
Any entrepreneur here, you got to write this business plan quick. Still plenty of room for another one in this industry I'm pretty sure
AU seems to be untouched as well

Nobody doing this there he confirmed.
