Some dealers will “burn” cars, report them sold when in fact they are not. They usually do this to make a goal and earn extra money. Being yours was “sold” in December there is a very high likely hood the original dealer did this to make his 1/4’ly and yearly goal. 55 days Is not alot, but after 15 years they had to call it. However if carfax shows first reg in July you have some ammo. Just don’t expect help from the dealer who sold it new as this may cause him to be charged back alot of $$&&
