Have been provided with this quote for ABC - too expensive?

[salis2]

Hi guys,

I have a few issues with my CL and I was offered the following quotes (am based in London, UK) - can you please let me know if these sound right to you?

- There is a rattling sound coming at low engine RPM - I was told ABC pump needs to be replaced. Quote is £800 + VAT (refurbished/remanufactured unit from Mercedes), labour is £500 + VAT and also additional cost for fluid

- Both front lower suspension arms have excessive movement in ball joints. Quote for both arms is £350 + VAT and labour to replace them is £150 + VAT

Also, would you recommend any indie garage in Central London or South London?

Thanks a lot!

i got a recon pump from one of the online spares places maybe GSF for about £325.

Took about 3 to 4 hours to fit, hard to get at tucked away at the side of the V, then you've got bleed it.

Front arms can be quite difficult to do, as there are 2 set screw at the bottom of each strut which seize in.

Pair of aftermarket front arm were about £250 from memory.
