Sorry that is not correct.
The M-Sport uses Bilstein shocks with eibach springs and soaks up poor UK roads far better than the cheap and nasty Boge/Sachs set up on the SE.
Also the sidewalls being stiff are the problem with the run flats and thus, 18's and 19's are actually more compliant and more comfy than the 16's and 17's.
Best ride so far is the M-Sport with Micelin Pilot Sport Zero Pressure 18" tyres, worse ride is an SE on 17" Bridgestones.
530d M-Sport from March 2007 is a nice ride and with the new gear box will return around 38mpg compared with 30mpg for the previous one.
I nearly didn't buy my 535d sport touring because of the interior, but once you get to live with it I think you will change your mine, I loved mine.
This was mine...
Only thing I would have changed is probably the aluminium trim, prefer the black ash or Piano Gloss black...
I would definitely try and get one with the HUD, it is a fantastic option for anyone that does a few miles or travels abroad, switching your car so all reading are in metric so you get L/KM, KMph, Metres till next turn etc. is spot on.
Also, I would forget the run flats, buy the emergency wheel and a set of 4 Falken FK452's, will cost you £500 all in and the ride is sublime.
However.........I am going towards the Merc!
As a big estate the Merc seems to suit it better, just a shame the E320cdi feels so sluggish though, but hey ho, it is very comfy, a nice interior and makes you keep your speed down a bit.
Audi Quattro. Please don't get me started on them, quite frankly the most dull and boring car I have ever owned!!
I absolutely detested mine!
Don't get me wrong, love the image (well used to even that is going downhill fast, every one sat on your **** in the outside lane now seems to be an A4 2.0tdi driver!!) and the design, plus the interior is well put together and the nav is good, but they are horrible to drive, I think they make sense for those that need a 4x4 but don't want a traditional one, but why people buy them who don't need it is beyond me, I fell for it once and never again!!!
My old one...
So to sum up, with a Merc you waft around in comfort, with a BMW you tend to hammer it everywhere with a big grin until that camera flashes you again and with the Audi you either understeer into the wall or just crash into it because you have fallen asleep through complete and utter boredom!!
All just my opinion of course.
