Quality and Money for Value Car

I own a Tata Harrier XT variant, bought it on 16 July 2019, by far completed 5 months with my car and just a 3400 km, I know its less to speak about but it's about the quality this car gives, I have a 3.0l Fortuner and this harrier feels much pleasure to drive, it was priced 18.50 lakh on-road to me, did some cosmetic work on it for 50k and now I cannot describe how amazing this car looks! by far my review is this car is good but lacks some key features from its rivals that is mg hector and Seltos like a sunroof and it has less power compared to its rivals but when it's in its sports mode then I cannot differentiate driving a 170 ps car and a 140 ps car and sometimes I think the engine loses its capacity to deliver power it's like 2-3 seconds less and this I pretty disappointing had issues like power window circuit was damaged brake liners rugged out too quickly in 2 months and its infotainment system had major sound issues, however, got it repaired from showroom and till now I've faced zero issues, about mileage I will say that car shows me 19km/h average but I can say it can give 15km/l in city and 17-18 km/l on highway in city drive mode and can give much better mileage in economy drive mode by far whenever I start my car I gives me the same feeling I had when I brought her home! amazing work from Tata.
