Over the last few months my ride has become bouncy, harsh and ‘crashy’ when on anything but a perfect road. So I’m guessing it’s time to sort out the tired suspension (Y-reg on 80k).
I’m looking to replace with OEM as the car spends most of its life on bumpy country lanes and speed humps in London

One of the many threads on here says new OEM shocks and springs all round should be around the £750 mark for parts.
I’m also thinking, while at it, it makes good sense to do all the bushes (yes, many of them I know!). But I know at least some need doing (‘rear wishbone bushes worn’ came back on my last service report). Again courtesy of another thread thread I’m thinking about £250 for a full set of OEMs.
So, questions:
1) all in I’m guessing about £1000+labour. Does that sound realistic?
2) are there any other option people would recommend instead of OEM (bearing in mind I don’t want a ride height drop or anything harder)
3) Any chance of getting any of this under warranty?! Or anybody had any luck doing so?! (Direct/Wise, can’t remember which I have)
Cheers!
