Hi Stewart, we thought the 4 seater because we were standing in front of it on the dealers forecourt and thought - "oh yes, extra luggage, not just knickers and toothbrush". I have always loved the rather alternative shape, with four adults n place it bottoms out all too frequently and so I imagine the designers were thinking small children. Whatever was the concept, our plan for the two of us is to tour and the additional space will be invaluable.
It's certianly great for the extra space and I know I'm in a minority (as 4 seaters are in a minority) and other Mog owners don't quite believe me when I do say that I actually prefer the long lines of the 4 seater especially when I have the tonneau cover over, sans side screens.
Espeically the post 2005 4 seater with the extended back with the rear scallop up from the rear wing
Mine looks even longer now with the rear luggage rack projecting off the spare wheel
I know quite a few 4 seater owners that have the problem of bottoming out with 4 adults in. A couple have been driven to disapir and have had to have new springs, shocks and antitramp bars to help fix the issue. One of my firends was even bottoming out with just him driving the car and put it down to the extra weight of the body cantlivering off behind the rear wheel, it was so bad. His was one of the first new shape 4 seater Roadsters from 2005 so maybe it had softer springs before Morgan realised it was an issue
Thankfully I've not experienced it at all dispite having 4 adults in touring Northumbia last year and sometimes taking my two sons aged 20 and 18 out in the back
My last 4/4 4 seater from 2000 did bottom out occationally with the boys in the back and I did have to go slow over bumps until Lifes Motors put some new shocks on the back to firm it up
Not sure why my 2008 doesn't as it sounds as if your Mog has done about the same amount of miles as when I bought mine 20 months ago and the springs should be the same from around the same time period
It's one of those Morgan mysteries
Ive just put new Avon Av7's on but only because it repalced the old Avon AV5's which were on it since new
I did quite a bit of research and it threw up lots of good alternatives and I was very close to putting Yokahama Advan Neova semi-slicks on because I loved the tread pattern and they have just put those on one of the new press launch Plus Sixes but I chickened out last minute through cost and went for the default Avons
With the 15 inch tyre you have more choice than my 16's and I dearly love the look of the classic tread Michelin, Dunlops or the Blockleys that Phil Royale has on his. The classic tread pattern and vintage looking tyres on Mogs look the bees knees
(you can tell I'm more infuenced by aethetics rather than all round performance)
