The truck I was interested in had a VIN that was photographed with my iPhone and then later checking their website, it showed that VIN as a completely different truck, SILVER not WHITE.
For a 2013 Silverado WT extended cab 6.5' box in excellent shape, they offered 12 grand and my truck had 75000 miles plus is a four by four; right off the bat, 'operators' type salesmen. Even got a call later from the sales manager inquiring whether I had been treated fairly... maybe, in the dark interior of the sales department, they were having a good chortle at the 'deal-making' going on outside, like a yuckity, yuck, yuck...
Wouldn't trust lending them a dime with a string attached through its center!!!
