looking to buy s15 spec R, wise choice. the boys r rite lot to consider when thinking of shipping.
I spent 4-5 months looking into one before i bought. Big worry of mine when shipping form Japan is that on the boat over, parts do get stripped and replace with spurious parts as the guys working on the boats know in advance what will be coming and have spares to hand and will swap out parts has happened to few guys i know,
England is a good spot to buy (epically as u live in the north u wont be hit with as a high tax) most have a very good serious history and well looked after, i dont know what the tax is on bring into the north. i know its less then south. 5600euro tax if ya land in dublin harbor and try for a southern pate. there is a spot 20miles form dover harbor in england tends to have some very clean ones from time to time cant just remember the name of the top of my head but when i do ill post the link for ya. YA can buy and drive to dover and ferry it back to belfast.
carzone.ie not a bad sight either alot of over priced ones on it though. i found that ringing up garages and offering cash they were willing to drop price even up to thousands with the way the country is people r finding it hard to sell (its a buyers market not a sellers ) and i did remind them of that and was able to get a nice bit off.
i have a good few sighs saved on my pc somewhere, of people selling s15 when i find ill post.
best of luck with it though.
