Thanks for that Kees!
Your rear bumper is original, but the front has been replaced at some point, as it should have the washer jets - unique to the s1.5 VDP and the V8S - and the rubber strip.
Your gear lever has also been replaced at some point, as it should be the s1.5/s2 one, not the s1 version. That's quite interesting.
It is a nice car, and a rare one too. Good luck with it!
