The NADA blue book has a VERY generous opinion of TR6's.
IMHO I think a bit too much.
I recommend the local newspaper for advertising. Reason being, one of my buddies has tried to sell his 1974 Tr and he's gotten a dozens of tire kickers. It was out at one of the busiest places in town. Most folks just wanted to hear it run and take a free ride. He got smart about the BS'ers.... Had every offer from trading "genuine" Rolex watches, boats, other cars to those wanting to make payments...Can't blame folks for trying....that's how others get scammed.
At least using the paper you know they read it, are interested in it specifically and have an idea of your pricing.
It is the right time of year to offer those "wind in the face" type vehicles. Bottom line still remains....CASH is CASH. Enough fake cashier's checks, fake personal earnest money checks and such floating about these days...So, CASH. If you have large amounts of $$$ trading hands - arrange for your final transaction in a bank lobby. Cameras are good things!
Be smart, do well.
Good luck!
