Let me give you a little advice. My parter deals in Ferrari, Lambos, Aston's etc. I, vintage Porsches...the kind you only see in magazines.
We always price them. When you play the game of make an offer, it makes the buyer an ex buyer. Don't play games, it gets you no where.
If you go to Trader Joes, they don't ask you to make an offer. I've been doing this for over 30 years.
So, someone makes an offer, you reject it, It inuslts the buyer. As for the ones outside.......a slow death.
I sure do like that blue '66 Roadster, that and 40K + to bring it back to life with a body off.
