Whats the gear change like?
Do the engine revs rise on their own when changing up or down each time you dip the clutch?
I haven't experienced anything like that reported by others, it's a great manual gear shift car to drive. I selected manual because I prefer to have control over gear selection. I also read a review (can't remember where) that suggested the A200 petrol 1.3 / 163 bhp engine is better suited to the manual gearbox.
I think having the AMG-line spec is worth it for the multi-link suspension (in preference to the torsion beam on SE & Sport specs). I think that (as well as using Comfort suspension option) make the ride over poor road surfaces acceptable despite having 19" wheels.
Another view I've come across is that the A200 petrol engine is harsh, but that's not my experience. I selected petrol because I will only do 10,000 miles / year including some shortish journeys.
