I can hardly believe this thread is over five years old Tom!
Equally nor can I believe it took so long before I discovered how much more comfortable suspension seats are. I don't do the mega mileage that I used to these days but they're still worth having. Occasionally I help a friend out by driving one if his Sprinters for a day or two, it's surprising how different a standard seat, a standard headrest and fixed steering wheel are.
If only a few of those option boxes are going to get ticked you won't regret:
- Suspension seat
- Comfort head rest
- Arm rest
- Cruise control
- Adjustable steering wheel
- Auxiliary heat of some sort
- Air conditioning
The rest you can manage without!
