Hi all, have a weird one for you. Bought an 07 E63 about month ago with 100,550 kms. I have barely driven it because its my second car. The other day I get in and its reading 109,xxx kms. Thought I was going crazy but I know for certain now that it jumped.

The car came with a full tank of gas which I only used up the other night so maybe have put on 600kms if that. It has also been parked because I want to do oil change before I daily drive it and the PO windshield sticker said replace oil at 103,000kms so I knew I had some time. So I know I'm not going crazy and mileage should be around 101,000 kms. Anyone know what the heck could be going on to rack up kms like that??
