I have owned a 1.1 2009 eco active Panda for about 10 months now, I do a weekly commute of 120 miles each way plus day running.
About 50% of my travelling is on 'B roads and country lanes.
Pro's
economical (52mpg on a run, 45mpg in town), narrow, well built, spacious internally for the size, ease of driving, light steering, good brakes, good heater ( mine is not air-conned, but isn't that why opening windows were invented!)
Cons
suspension can be a bit harsh, seat in mine not adjustable for height. the narrow build can make it feel unstable on certain corners, but that may be due to suspension issues that I am about to address.
Faults that I've come across with my Panda
The wireing on the ECU, on the type with 2 inline plugs, is heavy and not supported,this stretches the connections in the plug, either causing a broken wire or loose pin, strangley, always to one of the coils, this can cause the engine to run rough, cut out or not start at all and also brings on a MIL warning with the codes of coil failure and/or power supply failure. it is a simple fix. by soldering or making a strong-arm to support the wireing (which I have done temp out of a wooden spoon handle! soon to be replaced with some electrical conduit).
There is also a junction within the wireing loom, originally it was a plug type connection but was changed to solder, unfortunatley the factory solder skills wern't great and this point can suffer from a dry solder joint, again easy fix and its on the supply to the coils again (red/white wire)!
The above faults may be the reason the previous owner sold the car, but I have read on the forum similar issues for 2007-2009 Panda's
Another issue to watch out for is the rear suspension spring pans corroding out, I preserved mine within a week of owning the car, I am also about to change the front wishbones as the bushes are on the way out, this may solve the unstable feeling mentioned above.
However, a great car and probably ideal for what you need as long as you don't want to drive at high speed and use wheel spin acceleration..........
