Whenever considering any old bike - look at the surroundings. Well kept home/garage? Probably a well-kept machine. Area looks like a dump? Pass it by. A well-kept GL1100, 1200, or 1500 should go 200k miles with little difficulty. Alternators would be major failure, and although requiring engine removal it is a straight-forward job. Carbs are fine if ethanol is avoided, stabilizer used, and regularly operated. I'm a fan of the 1000s, but the others are great, also. I also ride an 1800 that we've put 114k miles on so far.
