I would definitely ask them first if they will honor your incentives before you cancel. Since the EDD when you placed your order was up to March 2024, they may consider the delay on them and honor all the promotions.Still no VIN on my Model X Tax Edition.
Ordered 2/24, estimated delivery date Feb-Mar 2024, then March 2024, then March 18th-April 22nd and staying steady there. Will cancel my order on 3/31 since I will lose all incentives at that point--free FSD transfer from my 2020 Model Y LR, $1,000 off for Cybertruck reservation plus 10,000 supercharging miles for trade-in and purchase. I'll keep the Model Y at that point as there is noihing wrong with it, and not worth the hassle unless they guarantee me in writing I will still get all the incentives. Plus I have 46 Tesla solar panels and a Powerwall and just applied for early Cybertruck order since I am a qualified Tesla shareholder. Figured I would have had at least a VIN by now based on other posts from people here in Denver area.
I have my MXP order on hold at the moment because I don't really need it and I don't get much of the incentives. The funny thing is I got the invite to get the foundation cybertruck yesterday and I am seriously considering it, although I would rather just get it minus FSD and the other stuff and save 20K.
