I sold mine just 2 months ago, wιth 440.000km (350.000 of them on LPG) on the clock and zero mechanical issues.
But, procuring certain spare parts had become extremely difficult, if not impossible, plus the automatic a/c had several issues that required lengthy stays in specialized garage plus A LOT of money compared to its price, so I made the decision. Still, it got me back 1.700€ easily.
Initially, I was thinking of a Panda 1.3MJ as a replacement, as it was my wife's daily drive (I have a 1.6 Multijet Tipo), and I honestly consider it to be the king in its class, but boot size was a no-no (we have two children), so we got a Renault Clio V 1.5dci for my wife and she loves it.
P.S.
Yesterday, I was browsing through car.gr and I got myself looking for 1.4 3D Stilos... It's just a shame that there are so little left out there.
