IADNATL - but you can purchase a vehicle and then lease it to your business if that is what you want to do. I have a partner who would buy cars in cash and lease to the business (at a fair market value). Sure - you are supposed to pay taxes on the personal use of the vehicle but that is probably true whether you have a conventional lease or not.
So you buy car for $90k. You act as the leasing company and charge your business $1500 a month for the lease. I am sure it gets more complicated than that and it isn't something I do. A leasing company certainly does not need to be the car manufacturer. If people really have a problem writing off the lease, I am sure that someone could create a leasing company to lease the Tesla. All you do is set the residual to 40% after 3 years to cover the risk of Elon/Tesla Bankruptcy. The huge savings in taxes would make the extra $150 a month in payments worth it (and you would get it back in the end).
Even Tesla's website uses a tax deduction in figuring the TCO. So really are people who own businesses and use the car for business really not writing it off just because they don't have a conventional lease????
