Do you own this bike?

Doubt anyone will see this since bike is outdated, however if you are looking to buy this used (or even new if you find one) then go for it.

A bit of background:
-I own this bike for nearly 4 years now and its been in use 70%-80% of that time. Used it very regularly, at high speeds on and off roads, up hills, bumpy tracks and also numerous small- medium jumps.
-Take good care of it, use correct bike lubes (Muc-off, WD-40 for bikes and universal grease), still have the same chain, casette, deraileur, rims, bearings and front suspension.
-Storage conditions varied: most of its life it has been outside either covered or uncovered, sometimes kept in shed or indoors. No signs of corrosion anywhere on bike (apart from suspension+chain but ill explain)

Pros:
+Extremely good durability of, well, everything
+Each ride no matter how rough is smooth with correct care
+The paint and details still nicely visible even after all that use, obviously some signs would start to appear. Been using mucoff all round lube&protect to clean and coat the frame once in about 2 months just to keep colour nice.
+With correct calibration, gears work perfectly with no signs of re-calibration needed since nearly 2 years ago.
+Brakes suit the bike perfectly, mine still have the same pads from new but rear brakes need some attention after all that time
+Fork is very nice for casual biking, however i need to upgrade mine due to a different preferred ride style.
+Quite light due to aluminium frame, I think its roughly 12-14kg
+Frame is also very, very durable. No signs of cracks or anything as such
+Extremely agile thanks to moderately wide handlebars

Cons: (pretty much depend on riding style and amount of care)
-Front forks are REALLY meant for casual riding. No jumps bigger than 1 meter max due to short travel and danger of damaging springs
-Front forks again need to be looked after frequently ie. taken apart every few months, seals cleaned/replaced and lubed properly to prevent water and rust buildup in spring tubes (such as mine, another reason for needing upgrade)
-Gears may be a bit annoying if you tend to use the whole spectrum, eg. pedal gear 3 (biggest) + rear wheel gear 8 (smallest) may cause chain grinding
-Use a chain slap guard as chain hitting the frame is inevitable, but im pretty sure this applies to nearly all bikes
-Paint wear/tarnish is quite frequent if you have something hard rubbing on the frame, such as a bike lock
-Pedal bearings tend to let go after roughly a year. Replaced mine with boardman flat metal stud pedals.
-Handlebar grips get worn quick especially if gloves are worn and in warm weather. Recommend fixed screw on grips.
-Brakes need bleeding since they are hydraulic. Havent bled mine since new due to lack of proper time so the rear brake is soft with low stopping power. Whoops (still work though)
-Not suitable for constant use in high intensity tracks since suspension might die and the chain slap would break the chain + ruin rear wheel arm beneath chain

SORRY FOR SUCH A LONG REVIEW. Just thought I would be helpful to that 1 person that might read it in the next 10 years :)
