I never got a letter...but I did actually listen to an add for Green Chevrolet in Peoria, IL...they advertised invoice value on trade-in on cars within the last 10 years. I was like "ok, we'll bite"...so we stopped in w/ the '96 T-Bird. Suddenly there are "age deductions" and "mileage deductions"....and instead of the 14K or so I was expecting to hear...we're talking about maybe $3500. I was like "false advertising some?" Then they tried to get high pressure....we walked...wasted enough time at that point. They are mostly all liars. Car dealers tend to be of two categories....nice or crooked. Doesn't really seem to be any in-between.
