£373 per spring is absolute frucking robbery. When I was trying to source genuine AMG springs for my car I was working in the USA ,
Mercedes Benz Modesto in California managed to find 2 springs (front) in the whole of the USA. Due to logistics and time limitations I declined to order them .
I then approached
Eibach (UK) , they are the suppliers to MB AMG who directed me to
Eibach Germany who refused to sell AMG springs to me.
Long story short , with help from MB of Newcastle upon Tyne (check out their
Ebay shop) they managed to source 2 genuine
Eibach MB AMG springs from Germany shown in post #69 for £215 (for both) incl VAT and delivered.
Note , this was for an 'oddball' car , C55's are oddball when looking for certain parts , in comparison (no offence) but buying springs for a boggo 2010 212 should be a piece of cake in comparison .
It's your money but IMHO someone is taking the mick trying to charge you that much for springs.
