Mike, you must live in a time machine! I remember having both a Grenada (yeesh!) and a Dodge Diplomat like your Elite...save my Dodge was the ever-present sky blue. All I needed was a leisure suit and Ricardo Montalban!
Those are some great LP's, and you snagged 'em good and cheap, but here in OK even Discwasher'd LP's don't seem to command more than about $3..sad, given what we paid for 'em new...LP's just don't appreciate like good equipment does!
I hear you on the hobby shop thing...I was into "N" scale trains till the prices went ballistic, then I concentrated on my Impala and my audio equipment...the scary thing is that I'd like to branch into some (ok, one piece-an amp) tube gear, just 'cause it looks cool...and VERY 'spensive...sigh...
