Lovely if you are in that position, but what about if you didnt have the extra £5k and high £20's was a stretch, i bet my left nut you wouldnt say no and thats exactly why imports are/were popular, they bring cars some people couldnt afford into budget and eventually, prices between the 2 level off, hardly any difference between uk and jdm 350's these days but i bet there was when they first came over
According to what you say re pistonheads ads there is no difference with GTR prices now (£35k uk, £33k import).
It's nothing for a car that needs a service every six months, eats tyres and does 15mpg if you drive like a saint.
If the uk car you mention needs tyres and the jap one doesn't they're virtually the same price.
