sure it's not you selling them? how come you have an aristo and you are looking for altezza coilovers? plus it's your first post!
anyway, aside from that then go for £1500 + new here but I doubt i'd bid on that auction as it's a new ebayer in a foreign country (to most of us) and the risk involved incase they are damaged or severly worn to me just doesnt seem worth it. by the time you've won, paid shipping, duty % vat and then paid for the spanners and tools to adjust the damping too much hassle for me
