Most likely suspension spheres. £200.00 - £300.00 fitted which should be OK versus the price tag. Get a diagnosis from a main dealer ( or two ) if you can. If you have a specialist independant , as we do in Plymouth, then you should save a fair wedge on labour. I lived in Ireland for two years. The roads in the north are a bit rough but mostly OK. If it was was used much in the south then you can halve suspension life ( at least ).
