The "normal" way to get a Race Modified car is to buy a premium model, change to it, then do the Race Modification in the GT Auto section. Since you changed to it, the change counter increments to 1 which means 0/0/0 should be impossible to have.
PS : 0/0/0 means 0 changes, 0 km/miles and 0 wins ... a brand new, untouched car if you will.
