Depends on what your doing with it. If you want to flip it I wouldn't be in it over 45-50k. If your wanting to be the end user then maybe 55-60K.
Allot depends on what the car was, Barracuda or Cuda, Small blk or big blk. People will try to tell you they are worth this or that, but right now, today, NONE that are selling are selling for more. People still ask lots more but they still own the car and will continue to own them unless the market takes off again.
I go to at least 1 auction a month, Kruse, Mecum, Leake, ect. Yes i flip so people here hate me lol. But I sell 90% of everything to dealers. Don't believe for 1 sec the bids at auctions. Until the reserve is off they will bid them against the wall to "create" interest so they still have a chance to make a deal even after the car no-sales on the block.
I know on one of my cars, they had 1 guy bidding, kept working him against the wall till he got to my reserve and sold him the car. Car sold for over 140K and he was bidding alone after 110K and didn't even know it.
The auction house is there to sell cars. If they don't they make no commission, the seller quits bringing cars and if that happens then buyers quit coming, big circle but necessary.
