Is a Muddy Fox Rock n Roll Rage a good bike? Anyone know original price ball ground?

Got one from a charity shop and love the feel of it Is a mountain full suspension bike like this a lot heavier than a racer? I read fat girls on mountain bikes are not to be underestimated lol At what point do people buy serious racer type bikes? Think I'm ahead of myself

 

is it 10 years or more old ? you would be rockin n' rollin on something more recent for sure ! especially on the mtb section, they have come a long way until today

 

Any ideas on how I can find out when it was made?
