Why are we working on the basis of a 4 week delivery? My dealer told me its 4 weeks minimum, could be up to 6 weeks. I know your Dad got it faster but that was highly exceptional circumstances that I doubt will be repeated. Given that every single estimate VW have given us has proved to be on the optimistic side I think we want to be careful here.
We've also seen that BW37 could mean up to "practically" BW38. My personal estimate assumes build is not completed until Monday BW38, then adds 4 weeks for delivery, which puts me taking the keys Monday of week 42. If delivery or build turn out to be longer this could hit last week of October or even November! If delivery is fast and build is early week 37 then I could get hold of it 1st week of October (week 40) but its mad to hope for this given VW progress so far. Even my dealer is talking about "mid" October (week 42)...
I think however you cut this 26 weeks (with potential for slippage) is what should be expected in my case.
I ordered 3rd week of April, but I know Jimble was before this so he is probably me + 3 weeks (which puts him on 29 weeks I guess!). I doubt anyone is worse off than that, but willing to be proven wrong if there is another unlucky soul on here!
