A simple summary is that a vehicle with a well controlled and modulated system of limiting slip on the drive axle(s) will always provide more ultimate traction than an open diff. system, whatever the electronics.
I think this is the point where I am coming from. We are talking about the extreme end of the traction area. If I go for the LSD so that I can get more power down in less than perfect conditions, or if I take on track days, then I would also ensure I need the braking capability too. So that means the PP as well. The argument for having one without the other is fundamentally flawed.
I have not purchased this car to attend track days, nor do I feel it needs to provide ultimate performance. We really are talking percentiles here and I have not seen justification for this item.
Resale value...........That is not considered in this purchase. It will be worth whatever its worth, whenever I get round to offloading it.
It will be looked after and will be very low mileage. It also won't have any track day frippery with which to scare off some buyers who want a proper car which has not be thrashed to within an inch of its existance.
If the weather is anything other than good, this car will be used in the sensible manner that any other car is. I can drive in normal ways in less than ideal conditions.
I could have bought a number of cars around the price bracket, but the usefullness of the loadbay, the lure of the V8 and fact that most traffic light races will been beaten into the ground without me having even to move, coupled with the fact Mercedes have at last raised the engeering back to the levels it used to have mean that this car is a compromise in some terms but appears to tick all my boxes. And its not a satan fuelled tractor engined version.
If I want ultimate performance, then I should buy a proper sports car.
So thats LSD's put to bed. Thanks for all the comments and the reasoning and some of the decent and interesting posts on it, but its not sold itself.
The colour does appear to be Grey. (And in fairness to Andy, if I see a red one in the flesh before I have to nail the order, you never know! Red is my default choice of colour for a car)
I notice not many have expressed an interest in going for a "spin" in it.
