That really should have been a page in the brochure:
At DeLorean, we use a lot of glue and wood. Don't freak out though, it works fairly well. Every emergency kit includes a jack, spare tire, Elmer's glue stick, a stapler and wood saw.
I remember the first time i actually noticed the parcel shelf wood I had a small panic attack. It was only after the transaction was complete and I thought we had been ripped off... until i did some googling. I even had a copy of the DMC technical inspection sheets when i first looked at the car - but of course they don't mention anything about wood.
