I was a manual, Grande Punto owner until about 2 weeks ago.
Swapped the diesel for a smaller, duologic 500 and I'm absolutely thrilled.
It's so much more relaxing. I don't know whether it's because of the lighter steering and the fact the car is a petrol, but the duologic gear box for me is a massive plus.
In traffic for example - in the Punto you'd have to keep your foot on the clutch and brake and be alert to keeping it in gear one, for fear of getting horned by the guy behind you in case you left the hand-break up and took your foot off the clutch.
For some reason, in the duologic, you can take your foot off the break when you're on a flat road surface, and the car won't move, front or back. You stay stationery! My foot already feels healed.
Brilliant gearbox. Had no problems.
