Yeah that’s fair, no point buying something not to your taste!
Are you looking for something as stock as possible, or is anything up for consideration? There’s one for sale on the UK S15 Owners Facebook page and it’s £9k I think but it’s very modified.
Unfortunately that’s something you’ll find with lower priced ones - tend to have a lot of mileage (or there’s something actually wrong with it...). Not necessarily anything to worry about if it’s been serviced properly and everything checks out, but if it was imported with high mileage you’ll probably never know what it was treated like in Japanland... downsides of imports eh? Mine was supposed to have been “freshly serviced” when I bought it but it still had the oil filter from its service in Japan haha.
