Mine blended on a monday, was built on a tuesday and arrived at the dealer on wednesday. I didn't pickup until thursday because it caught me off guard being that fast. Now, mine is not your typical timeframe. There's a lot of factors that go into it. Being 30 miles from the assembly plant helps.
Opposite end of the spectrum... built august 29th, shipped November 15th, still waiting on delivery TBD? possibly before the end of the year? No real standard timeline wise, goodluck though! may the odds of speedy production to delivery be in your favor
I had one blend 3/28 built 3/30, wait to mid-June for truck to ship, showed in transit 1 day to NJ, available for pickup mid june, so 11 weeks total.
My other was mid-august blend, built 2 days later, shipped rail 1 week later, arrived at dealer in TX 2 weeks after that, so just about 3 weeks-ish.
As others say, it appears all over the place. It is getting better with longer delays less common....though I expect a rail strike can really mess things up.
About 30 days here. Loaded at MAP quickly but then 10 days of the train shuffling back and forth between OH and IL, 9 days to get across the country to northern CA, then another 10 days for final trucking.
