What am i doing wrong to get junk cars???? - Page 2

ok got ad up on craigslist and i'm getting calls. but when i get a call and they ask me what i will give them for there junk car? i look up the curb weight x what the price they're getting at the scale -100. and seems like there answer is ok thanks or they say they will call me back = no thanks in my mind.
for example this morning got a call for a 98 seville. looked up the curb weight which was 4,000#. my yard gets $205 a ton right now. so $205 x 2=$410-$100=$310. so i told the guy i would give him $310 for it. his reply was ok thanks then hung up the phone. to me that means no thanks!

i'm getting tired of my car trailer sitting in the yard empty not making me any money!
last year i got into junk cars late in the season but made some money. so far this spring i only found 1 car so far and that one i found on craigslist! for the most part nothing!! so what am i doing wrong? anyone have an idea? be honest because i'm trying to learn from it so i can make some money.

thanks
