Morning everyone, the cash has finally landed in the bank and it's time to go get the slk. Unfortunately After 2 months of reading the forum and trawling auto trader my head has gone up my backside with all the alternatives. Finally actually drove a 200 manual yesterday and was very impressed. A lovely 54 reg 350 has turned up on eBay with full service history 78 k miles but all the balance shaft horrors are concerning me. How often do they actually go wrong?
