Not a bad wee car at all, but I am slightly bias and therefore maybe a bit more forgiving than most! I currently own 2 Panda 4x4's and have owned 6 in total! The Sisley was a special edition designed by Benneton, and are getting rare nowadays. 4x4's do have their fair share of niggling common problems but if you can put up with it you will get a very versatile little car, on which almost everything may be taken off with a 13mm spanner!
Problems to watch for:
-Unmarked fuses on fuse box
-Headlight switches prone to failure
-4x4 Rear leaf springs prone to snapping at high mileage
-4x4 Transmissions can be weak if not looked after, change oil regularly, avoid using 1st gear in normal driving as it is essentially a crawler 4x4 gear and is too low for sensible on road use. Do use the 4x4 system regularly, to prevent seizure, even if it is only up and down the driveway!
-Sumps prone to damage
-Watch for rust below windscreen and around door corners
-Boot locks are poorly designed
-Gear linkages from stick to box are prone to working loose and breaking at high mileages
But look after it and it will look after you! The 50bhp engine is nippy around town and will often help you win the traffic light grand prix! Unbelieveable off road and does the type of stuff it shouldn't, more than holds its own with daddy Land Rovers! But difficult to get hold of, owners aren't stupid, are very loyal and tend not to part with them easily! Find a good one and enjoy both on and off road!
