It’s different I’ll give it that!
Finding online original brochures of JDM Edition 35’s doesn’t seem easy. I don’t recognise the spoiler but it looks like the sort of thing Oettinger or similar might have produced unless it was a Japanese domestic aftermarket part. Tastes vary wildly across the globe.
Are there any markings on the back of the spoiler Wadey?
How did the car end up in the UK and do you know much about its history? Does it differ spec wise from EU models in many ways?
