I was intrigued  by Marvin Peitz's note stating that 88-and-later GL's were
at least a foot longer than 87-and-earlier. I've owned almost every year
from 86 to 91 and never noticed a difference.  Having an 88 and an 87 in
the driveway at the moment, both GL's,I dashed out and measured them both,
headlight-to-tailight.  They were exactly the same, 169 inches.
