How many Wagon Rs have you seen flipping on Motorway or other highways? I haven't seen any till now.
Wagon R can also be a middle class man's car if he purchases high quality spares from market. He just need to find right shop run by an honest person. Maintaining even Cultus from 3S requires that you are a rich person making millions every year.
Just inquire about genuine Cultus CV joints and axles prices from Suzuki dealership and you will get a minor heart attack.
