Kia Cee'd SW 08 - Kia Ceed SW suspension bushes and rear coils - fuzzyduck

After looking at a few Focus and Fabia estates, I've got my eye on a Ceed SW 1.6 - 2008. My thinking is it should be reliable compared to other similar aged cars - newer and less miles on it for the money than the Focuses and Fabias.

Looking at the MOT database, it does have a few advisories as follows -

Nearside Rear trailing arm rubber bush deteriorated but not resulting in excessive movement (2.4.G.2)
Offside Rear Trailing arm rubber bush deteriorated but not resulting in excessive movement (2.4.G.2)
Rear coil spring corroded (2.4.C.1b)
Offside Rear coil spring corroded (2.4.C.1b)

I'd like them to sort it all out or ask for a proportional discount: any idea of a realistic figure to get the bushes and coils replaced?
