BMXmuseum.com Bikes / Mongoose / 1997 Mongoose Supergoose Comp

Back into BMX after 20 year break -- love it.  This I bought from a guy who said he got it about 10 years ago and his daughter rode a few times and that was it. I picked it up at a garage sale. I am getting into collecting and first learning about bike parts -- Everything reads mongoose -- tires, seat, pedals, grips, etc. After researching I do not see anything that is not stock -- I added the front brake and pegs for flatland freestyle -- Without those I believe it is fully stock. The seat needs some repair (not that bad) or replaced, but otherwise is very clean.  I am not positive of the year -- still learning about the serial #'s.  I think it is a '99.  I took a pic of serial #. Any info would be helpful. I am excepting offers if anybody is interested in any of my bikes -- need money to buy more -- it's addicting.  Info on any of my bikes would be much appreciated.
