If you have to have a smallish 4x4 car then consider a non-turbo Subaru (Impreza or Forester). They would be a lot heavier on the petrol than your Panda, although the later one (2005-on) are more powerful and economical.
We had a non-turbo Impreza and put 150k on it. Absolutely fantastic car, the wife and I loved it to bits. Just totally solid and reliable. Would have liked the turbo model, but couldn't afford the insurance and 22mpg economy, more's the pity!
In all of that mileage we only had to replace two driveshaft rubber gaiters. Everything else was just service items (timing belts, filters, brake pads and discs) and the trim and chassis stood up to the hard use very well. You could get a decent secondhand one for the price of you Panda. Running costs (mainly fuel) could be high if you cover a high mileage though. If you're a low miles driver then this would be much less of an issue. Subaru dealer servicing can be expensive, but you'll find a local garage can service a non-turbo version quite inexpensively.
