I'm looking at an 08 base unit GL 1800 (GL 18P) with 4000 miles. What are the differences between the 08 and 09 base units with no regard to new or used? I've just started to look at Goldwings and the factory specs are sorely lacking in describing the simple amenities (such as heated..., etc). I'm new to the forum so hope I'm asking the right question in the right way-the "search" function sure didn't work. Thanks for any replies!
