@JohnB5677 Thanks for your reply.
If I may, I'm going to add a bit more info regarding the individual rebates to see if it changes anything.
The $1000 rebate was a state rebate that used to be a post purchase rebate from the public utilities, but the process changed to a point of purchase rebate at time of sale.
The $500 rebate was a rebate from a third party for purchasing the specific brand of auto I did.
The $5000 rebate (was actually less than that, I can't recall exact number) was not a tax incentive to my knowledge, but actually a check sent out from a state fund encouraging buyers to adopt the use of ev's.
I guess what I'm getting at is when/what determines exactly if it's used to reduce cost basis? At time of purchase only, post purchase, mfr or tax incentive or ev incentives?
To your second answer, are you saying that if using the actual cost method vs mileage, then one can only take depreciation and cannot take other expenses such as tires, fuel, interest on auto loan?
Thank you for your time.
