Welcome Fliss!
Always nice to see a car changing hands and the new owner becoming part of the community, compared to some of the other owners clubs out there with the more common brands this place is bloody brilliant. If you haven't already, check out the Abarth Owners Club on Facebook, and if you're that way inclined there are loads of regional groups as well. I bet you'll find information on there a lot easier too, this place gets a lot less traffic than Facebook does.
The car does look very good, you should be in luck with it being well cared for. I personally had issues with mine, the previous owner did a lot of stuff himself, didn't seem to be that skilled, and whilst he was on the AOC (and the Punto Collective, we have a group just for us which helps us out massively
) made a grand total of one post. I'd imagine that even if the previous owner of yours isn't on the Facebook group anymore, someone will recognise the car and may be able to help.
