While the XGM is not widely regarded as an 'excellent' body, neither is it close to being 'rare', if its still working properly (accurate shutter timings, light sealed, accurate meter) it will serve its perpose.
It was not the best made body at the time, was somewhat of a budget series as far as i can remember. Look at rokkorfiles.com if you dare... I warn you though, its an excellent site and it can become addictive searching for the more exotic lenses/bodies!
Unless you're into macro/landscape there is no reason not to still with your body. If you want to do more critical stuff like macro and landscape (or want to make massive englarments) you will need mirror lock up. Some of the SRT bodies have this feature. They are excellent quality, fully mechanical beasts that seem to last forever! Im cleaning up a lovely SRT-303 in black finish at the moment in fact. They are very high quality contructed bodies, but do way a bit more :-). But if your XGM does 'go', you can always pick another one up for pennies anyway. Best thing is to just get out there and continue enjoying the ways of 35mm!
All the best,
