Baleno long term review

Using this car around 4years...drove 52000km...this is my 1st car. Overall I am very disappointed with maruti suzuki Pros: 1. For me Mileage is good...it's totally depend on you how you drive the car. I am getting around 22km/l on highway and 15km/l in city traffic....with ac on 2. Lots of boot space 3. Music system is good 4. Smooth gear change 5. Good looking 6. Good engine Cons: 1. Horrible built quality. After 9months I saw some rust at the corner of orvm area...after that found many places becoming rusty, when I complaint at maruti suzuki service center they took some pictures of rusty part and send those pics to higher authority for further steps...almost 2month later 2person again took pictures for repair conformation. After 3month they gave me a date for repair. And they just repainted those area to cover the rusty part....after 10month again those parts becoming rusty. After contacting them they also took some pic and this time and did not even contact me..after lockdown when I contact them ..they again took some pictures and send them to higher authority. They told me this time may be i cant get any repair because of it's almost 3year of my vehicle's age...after some days they told me higher authority has declined to repair the rusty areas. (Pathetic build quality...will never buy maruti suzuki again) 2. Suspension must improve 3. After 120km/h becomes unstable.
