Money waste

It is day  3 of my  car REXTON RX 7 AT. Engine is very noisy, lousy, maruti 800 can pickup faster (I m user of automatic version). Ac is unreliable, after sales service support is poor. 24x7 assisstance is total fraud. My AC suddenly stopped working on highway barely after running 120 kms. No assistance recieved, had to come back. Pl dont waste your money buying this product. Suspension is not upto the mark, softness is missing. Mahindras badly need to review the AC, and slugishness of this product, if they want to retain their name, looks are good otherwise both exterior and interior. navigation software of mahindra xuv500 is better than this "premier car" of mahindra. dealer network also needs to be strengthend. Very few people are trained about this car. Think thrice before buying than to repent later. Dealer refused to provide contacts of any senior person of mahindra, their website also has no provision for customer greivances.
