Hello all. I have just joined the MB club uk having recently perchased a 560sec 1988. the car has done 180000 miles and has a full service history but needs a little tlc. It has been owned for the last 21 years by the same guy who has kept it garaged and spared no exspence but having got the car home I have found that the transmission fluid is low is this a common thing and where can i get some. my local merc dealer stock it at £10.50 per ltr
