I'm new to bikes and not that great of a mechanic. If it were me, honestly, I'd keep looking unless the price got down to around 1200 as stated before. The bolt off of the engine disturbs me a bit. When you say the turn indicator didn't work, I assume you mean the little light on the dash. That should be an easy plug in fix for both of those bulbs.

As far as oomph, I'm no expert but I'd assume the carb has been sitting with gas in it for 1.5 years, and that might have caused some varnishy buildup. Usually on here, a tank or two of double strength carb cleaner, a la seafoam or chem b12 is recommended. That might pep it up a bit, as would the new plugs as mentioned here also.

The GZ is a very hardy breed, so as long as it is running good, and it sounds like it is, it probably is going to be just fine. 4900 miles is, of course, pretty low, so that's good, too.

If they have a mercedes, they probably aren't backyard mechanics, so they're used to paying shop prices, so if you mention you might need to replace the chain, tires, etc, that might get them down on the price. I don't think you'd actually have to replace the chain, but they don't know that probably.
