I have a rough gearshift with my UK spec '93 S500. Its particularly bad when Islow down almost to a stop and then accelerate - even gently on a light throttle - it really 'thumps' when it shifts - any ideas?

I also have a bad wheel wobble at 45 - 55mph. I've had all four wheels balanced and it cured it for a week and now its back - the whole car seems to shake.

TIA
