Looking to get into riding and would like to pick up a full suspension bike. I've seen an ad for the bike pictured locally. Understand that's it's quite an old bike and probably pretty dated by now, but would that be considered alright for a starter?

Their description is :

Trek Fuel Ex 5.5 Full Suspension Mountain Bike
17” Lightweight Aluminium Frame
Shimano Hydraulic Brakes (Front & Rear)
Bontrager Ranger Wheels
Continental Vapor Tyres 26 x 2.1
Rock Shox Tora 303 Front forks ( not sure these are a thing, can't find info on them.)
Fox Float Rear suspension
R1 Tuned Suspension
27 speed Shimano Deore Chainset
Shimano Deore Shifters
Bontrager Race Seat Stem & Saddle

They're asking £535, but are open to sensible offers, what would some of you offer for it, if anything?
