4x4's of that vintage use a completely different rear suspension setup; afaik it's the same regardless of whether petrol or diesel.Rust issues ok the rear axle 4x4 parts are likely to be the same if it’s a petrol or diesel.
The problem is that if it becomes seriously corroded, which is quite likely on a 14 yr old car, the cost of its replacement (even if you could get one) will write the car off.
At least with a 2WD car you can fit an aftermarket replacement at affordable cost if it rusts out.
Because the chances of finding a 4x4 Panda for £2k that's going to give reasonable service without significant additional expenditure are slim. If he's set his heart on a 4x4, he's going to need a considerably larger budget.Again no one is asking what car you would buy this person is specifically asking about the panda 4x4 that’s clearly what he wants. I don’t understand people’s need to find fault in everything and try to put him off.
