What am i doing wrong to get junk cars????

cars are getting harder to get now days...i always price them at 100 dollars less than my estimate of what the car will bring..i have always done it this way and dont plan on changing any time soon....i never add aluminum wheels or converters into what i offer for a car....in my area it is rare to get a car with a converter on it....even if it has one there is no guarantee it will not be burnt out some or busted up.....

latley i have had some luck hauling cars off for folks....what i mean by that is....if they dont like the price i offer them,,i will then say..well i will haul it in for you for 100 dollars...as long as its fairly easy to get to and isnt burried 5oo yards up a holler at the end of an old logging road.....ive probably hauled in 10 in the last few months on this deal and it seems to please alot of folks......also this way i strip absolutley nothing from the cars, all i do is drill one hole in the tank and thats it..so its alot less work on me....i also deduct 20 dollars off the top for gas on every load....
