I'd love to buy a second hand landrover defender (90 or 110), preferably with "a few toys attached" for the inner child in me e.g. winches/snorkels etc., and would probably look to source it from the uk.
I don't know if you are looking for a specific Land Rover dealer but sites like www.cargiant.ie and www.motorpoint.co.uk have a reasonably good selection of all types of used cars and have a fairly good reputation.
