Man I just got excited...
YES!!! That is a top of the line PowerClean in what looks to be in gorgeous shape!!! And for what a steal too!!!! Year is probably '99 to '01, you'd just have to have the model and serial. Mine is a 2001 as far as I know, and is just a step down from this model listed. GU940SCGB2 is mine.
Jump on this with both arms and legs if you can; it's still a brilliant machine and they're a lot of fun to work on. Parts are still plenty available.
I'll try to hunt down the threads where I restored mine last year. Good luck!!!!
