Frenchie

Four years ago when I ordered my SLK55 I was able to track its progress to delivery. I could follow it on the boat and I knew when it was on the truck as well as its ETA at the dealership. If memory serves, this was NOT an M-B site, but unfortunately I’ve lost the name and web address. Now that my next car has been ordered I’d like to track it. Does anyone know what site that was or if there are any sites available for tracking with the VIN?

Thanks.
