Hi Rob,yes was looking at the white slk but giving it a miss as the car has outstanding finance and is about 150 miles from me.looking at googles reviews, 28 people left a review 4.9 out of 5 bet not many main dealers would come close to that.
Are you thinking of the white SLK thats main dealer money so price may be a bit high for a independent.
Thanks,viewing testing a 2013 250cdi Tuesday,will make my mind up whether it's petrol or diesel after then!Good luck with finding one you like, should not be that hard and I am sure you will love it.
