I agree. And I probably wouldn't buy it if it was green.It think cars in a "good" color generally bring more money and are an easier sale.
Would a yellow '70 Hemicuda brind more money than a B5 blue car? I would think there are more buyers in blue than yellow.
There is a Cordovan poly brown 69 RR convertible for sale. It is a 4 speed ragtop amd most people I know would walk away from that car. As with all things color it's an opinion based on preference.
