I'm not sure you can rely on tax refunds either. For example, if you buy the car in your name and then you lose your source of income (whatever reason, e.g. health, maternity/childcare) and for example you rely only on your spouse's income, I know at least one country where you can't pass the tax benefits to the other person (not even by transferring ownership of the car)
