Hi, Ican't comment on the Electronic gearbox because I've never tried one but I find my manual box quite good in normal urban driving.The car has cruise control (and speed limiter) so is not onerous to drive on longer journeys and the 1.2 fuel economy is excellent when driven sensibly.
I didn't take the SatNav option on my car because I couldn't see the point of paying a lot of money for something that my smartphone does for free, and having read some of the comments on this forum about the Peugeot SatNav I'm quite glad that I didn't waste my money on it. It's worth noting that options such as Park Assist, Rear parking sensors, SatNav etc which integrate with the touchscreen can't be retro-fitted at a later date without complete;ly replacing the touch screen and its control unit.
