I have an 86 and the roof lineing started to come away, so decided to reglue it. Under the lineing writting with a green marker pen is " 10/22/85 86 #B". So what does #B mean, I gather the numbers are for the MM/DD/YYYY. Also went for a run down the M5, got 10.5 lts/100klms. going by the computer readout. :ado
