Ordered MME Premium RWD Ext. Battery the last week of May 2021. At the time estimated delivery was 24 weeks. By mid-November the scheduled start date was 11/15 then 11/22 then 12/6. I get it, this is not a science. On or around 12/8 the estimated schedule date changed to IN PROGRESS. Hooray, so I thought. Now almost a month later it is still IN PROGRESS. No chance of snagging the tax credit on my 2021 taxes. My preferred dealer said once it is marked in progress it usually doesn't take but a few weeks to ship. Guess not.
