Riding wise its good but quality wise its below average..!!

I hav bght this car 10 mnths ago. Riding experience is good. But the quality of vechicle is pathetic. complete interior is being getng bad so fast and most important during rainy season the boot of the car is gettng filled with water where even the spare tyre is completely sunk. and this water is spreading inside the car both driver side and the floor mat gets wet. Has complaint to the service centres so many time and have changed the service centres thrice. But they asked to change unneccesary parts and the complaint still exist. Bcoz of this problem the car smells like a hell and am gng to sell it soon!
