I still ride my '98 Stumpy, but no longer on the trails. It's my commuter I ride daily to work. It's gone through a paint make over, several parts changes and chain/cassette/ring replacements over the years. The only part that's show room floor original is the front Shimano Deore LX derailleur. That thing is bomb proof and the iron man of derailleurs. 13 years of continuous service, not bad for a $1100 (in 1998 dollars) investment.
Alas, I no longer have my first ever mountain bike. A '90 Giant Sedona ATX that was $350 (damn, that was a lot of money back then LOL!) at the local bike shop that no longer exists. It was rigid, steel, heavy, 7 speed and had a god awful Shimano Bio Pace crankset that I absolutely abhorred. On a side note - wanting to rid myself of that crankset introduced me to the wonderful world of bike wrenching. I loved that bike and rode the heck out of it. I still regret giving it away to my buddy many years ago.
