Goldfinch and Purple finch

The boss is looking for a new tractor. He found one at the local dealership and it only had 3 hours on it. (When talking used tractors you are more concerned w/ how many hours on it than miles.) He called up the former owner and asked why he got rid of the tractor. The former owner had seen this tractor advertised for $105,000.  An excellent price. The tractor wasn't exactly what he wanted but he couldn't pass up such a good deal and bought it. When it was ready to be delivered the dealership said they had made a mistake w/ on the ad, however, since all of the paperwork was already signed, they had no choice but to deliver it. The former owner used it for a short time but then found the kind of tractor he really wanted at another dealership and traded in this tractor making a $20k profit. This tractor has the automatic steering that the boss really wants but he's a little concerned that the radio's FM doesn't come in clearly.
