Guys, once your Defender is built, is there any way to get more information than just the carrier & RORO name & the estimated /
prospective delivery date?

I know once you know the vessel name, you can track it across the Atlantic using Marinetraffic.com or Vesselfinder.com and turning on the trial advanced level for the 7 day trial (otherwise, you can't see movement away from shore). I tracked my 430i BMW last year - and they let you see the progress details throughout the whole process.

I know VISTA2 shows some detail to those who have access - i. e. dealers.
