You will slowly lose interest in the Datsun 240s I went through this with a yard full of FC3's ..2nd generation rx7s....eventually everything turned mopar again....for 2nd time.....Mopar or No Car
I have one Z I can never sell as it means too much to me. I've owned it for 25 years and my grandparents owned it for 25 years before that. The others wouldn't bother me either way....they are worth far more now than what I paid for them.
