No only that but when I got the Jaguar at the end of the event it had LESS PR than when I built it in the event.
At the end of special events, all partially-built parts have their materials (gaskets, batteries, relays, etc) stripped off and you end up with a car that has lesser PR.
For example, if you had a purple 5 star engine during the event and you install 3 out of 4 materials required for 6 stars then finish the event you will end up with a purple 5 star engine with no materials i.e. you get to keep the part's color and star, not materials.
I guess it is best that you install materials in parts when you have collected ALL required materials, otherwise they go to waste after the event.
