No way I'm offering on something without seeing it first.
True story- I was looking for a Camaro, and I found one on CL. 79 Z/28, no engine or transmission, asking $1350. Couple pics on the ad, looked ok so I called and arranged to meet the seller and check out the car. Go to look at it, find out the cowl induction hood in the pic wasn't coming with the car, the Hurst Quarter Stick shifter that was clearly visible in the pics wasn't included and the windshield was cracked. After looking at the rest of the car (which was remarkably solid for a 30 year old F body) I tell the kid I'd give him $1000 for it. I had the cash in hand and brought my trailer with me.
The kid's father blows a gasket on me. He screams at me about wasting his and the kid's time with a lowball offer, tells me I saw the pictures and price on CL, and should have negotiated price before coming over. I kindly tell him the car was falsely advertised, no mention on the phone about the now not included items and/or the windshield being cracked. I thanked them for their time and left.
