However you look at the flip side, Near new coilovers, refurbed enkeis, near new wilwoods etc etc.
I could break it for a hell of a lot more, think i briefly worked it out one day and it was over 7k in bits.
I don't have the time for that. To be honest i could sell the enkeis, retrim the door cards and swap in some recaros and it'd be the same interior. - Enkeis mentioned in terms of monetary value etc etc
The only part of the interior that is EK3 is the seats & door cards.
Granted the engine i can do nothing about, however if i hadn't mentioned it you'd never know. I imagine that there is more than a couple of cars on here that have different engines than from factory. I would bet some of them the owners don't even know as they may have been done in Japan.
I don't think the fact it is not "the factory engine" that it should be a major issue. As it would have been "the factory engine" in another EK9.
If he's interested get him to message me and we can talk and see what he thinks. The price isn't set in stone but i won't be having my pants pulled down! As it where!
