It was either on this Forum or the Sky one. Someone was able to get window stickers for a large number of the cars. Maybe some will remember who that was or they may still be around. I think they got this information when the plant was closed. I have never heard that it was against any law to duplicate them, but the manufacture is the only one that had them. The Dealer will not be able to help as far as I know. I have mine in a drawer in my desk with all the maintenance records and anything I have added to the car (receipts) . In case I should decide to sell someday or just pass it along to a Grandson or Granddaughter.
