It's the labor cost that's a killer especially on the suspension. I can't tell you if it's worth it, obviously up to you. However over across the pond it's still probably half the cost it would be over here. Over here you might have have to take out a loan on your home.
2010, 72k miles and honestly drives a dream and other than these issues has been perfect. Had a slump recently where general maintenance has fallen off, ie worn tyres and things i’d usually stay on top off. But other than that, it’s all good. Had a garage quote me over £1000
Yes, worth fixing, can you do some of it?
Two new handbrake cables and some tlc should fix that, not expensive £30/40
Front suspension is quite doable better when it's warmer mind, about £150 in parts
Have some one do the lower control arm?
