Tax implication and gift deed on marriage gifts of "car"

The property definititon as per Section 56 reads as under:
(d) property means
(i) immovable property being land or building or both;
(ii) shares and securities;
(iii) jewellery;
(iv) archaeological collections;
(v) drawings;
(vi) paintings;
(vii)BB sculptures; or
(viii) any work of art;  
Since the same is not specifically mentioned then the same is NOT liable for taxation u/s 56
So whether car is received by relative or from other it's not make any difference the same will not be taxable.
For formalities you can ask your future "father in law" to give a gift deed along with Car.
