Car: As a practical matter, no.
You can deduct state income tax OR state and local sales tax, not both. If you deduct sales tax, you can deduct all the sales tax you can prove with receipts including the car. Or, you can use the optional standard method where the IRS gives you a deduction based on your income and location. You can add a motor vehicle to the optional method. BUT, New York's income taxes are likely higher than any sales tax deduction you qualify for, so as a practical matter, there is no point in trying for the sales tax deduction. (You can try, but it likely won't help.)
