I bought a new car in March 2017 can I get credit for the sales tax on my 2016 return?

Texas has a statewide 6% sales tax on new cars

Only sales taxes that were actually incurred during the calendar year of 2016 can be deducted on a 2016 tax return.  If the state sales tax is still a deduction for the 2017 tax return, it can be deducted on your 2017 return next year.
