Like to elaborate a bit Olly? By design or neglect?

I've had mine, a 57 R320L CDI, about 2.5 years, and apart from servicing, I've had a minor oil leak fixed, a couple of speed sensors and two rear shock absorbers. The previous owner had the electro plate issue sorted in the gearbox, which is a common drive train with the 7G box amongst other models, and it has clearly been looked after. All in all, a very tidy sub 80k motorway muncher.
It doesn't necessarily give you all the space you might hope for. It's a cavernous and comfortable cargo carrier, but not the best estate car for anything over four/five passengers if you need luggage space. My model has six seats which are comfy and spacious for all without luggage, but there's very little storage space between the third row of seats and back door. You can get a dog guard which separates good space behind the second row of either two or three seats, depending on which model you have, and the back door. The 7 seater will give you three seats, two large and one small, in the middle row. You would need the third row of seat space laid flat to accommodate passengers' luggage if needed. In the six seater, you can configure the rear seating to any up or down combo, and I'm sure the seven seater would be the same, but I'm not sure how the middle seat is installed, ie attached to the n/s seat or fitted independently.
Not the easiest of cars to park, and my car doesn't work well for five plus my father in law's wheelchair, which a seven seater no doubt would. I get typically 31 mpg on a run, mid 20s urban, which I don't do much of. They have been painted with the ugly brush, but the looks have grown on me, and I'm always pleased to see another.
