Last yr I learned a valuable lesson about this hobby & the internet. There was a car for sale in Alabama & I called to discuss it with the seller. He was looking to get between $XX and $XX for it, so I asked him to hold it until I could drive down & inspect it. I got there 2 hrs later & after inspecting it, told him I was interested enough to buy it. He then quoted a new price which had increased another $5k from the top price he'd given me over the phone. When I asked about the increase he told me 'anybody that has 6 figure Novas can afford another 5K bump.'
The info he got off google linked to this site & the Gibb/Harrell feature car that I once owned. I was stunned, but grinned at him, shook his hand and bought the car calling him one smart SOB.
