I had an 86 with every option except for the block heater. Mine even had the digital climate control in Celsius which led me to believe that it was a Canadian car. How many of those do you think there were? The intercooler serial number was 00052I have a 1986 Buick Grand National that has T Tops, a digital dash and climate control. I have looked around and haven't had any luck finding another with these 3 options. Does anyone know if these options were rare to have together?
