I was going over the old receipts for the 240 last night and have one for a differential front seal replacement done 11/15/01 at a dealer in Bloomington In. The PO paid 863.57 for this service. He had told me the dealer had done lots of work on the car when he was on a trip last year. He's not kidding, same dealer charged him 357.43 plus 55 freight to replace the drivers door seal!
