i think its safe to say it probably is a 6 speed one.i spoke to the old guy about it earlier and he normally deals in mercs,but got this as a p/x from a merc dealer.when i asked if it was 6 speed or smg he went quiet and then said "i think its a 5 speed-i took it to the garage earlier for an mot and service,but cant remember seeing a 6th speed!"

may be going to see it in a bit as its a 1 owner 40k miles one-but its boston green!!!it just caught my eye this morning in the auto trader.
