Dear Sir 

Learn to fight for your cause. Get proper receiving before handing over the car. demand your items back

You should give a befitting reply to legal notice received by you denying all the allegations made by her.

You should also address the counter allegations that she had stolen  cash and jewellery from your house and ask her to return the same.

Also, you should ask her that she can collect her which she had ababdoned at your place, within 15 days of receipt of the legal notice, else you would get it towed.

Ghar jakar handover karne ki koi jarurat nahi hai. It can complicate things and should be avoided.

you can also file a petition seeking Custody and alternatively visitation rights of the child is your wife is not allowing you to meet your child. Supreme Court has also held at custody of children above 5 years of age should go to the father, but the welfare of the child would be of Paramount importance.

you can file restoration of conjugal rights petition in the family court requesting the court to direct your wife to come to her matrimonial home.
you can file custody of child petition in the family court, in that case court will immediately provide visiting rights to you.

See you can deny the allegations in the notice and can further give her notice to come and restitute her conjugal rights as she has deserted you. Further if she fails to return on the notice thn file RCR and also a petition for the child custody. 

See you mention in notice that you are not using car it is standing there she can come and can take it if she wish so. 

If you have received a legal notice then you give her a reply notice  denying the allegations made by her and may state that it was she who had abandoned the matrimonial home with out any valid reason hence it is she who has to return to the matrimonial fold immediately or you may proceed legally against her.

After that you may file a divorce case if it is no more possible to continue the married life with her on the grounds of desertion and cruelty

you can inform her that the care is lying at the same place where it was lying at the time of she leaving the matrimonial home hence she may come and pick it up with prior intimation to you.

Dear sir

Yes you have to hand over the car to her but in front of some witnesses so that in future you don't have to face allegations of not returning the car.
