Never ever do dry dusting your car. Drive with dust is good enough to wash it later with car shampoo and wash mitt. Always use microfiber cloth for car cleaning inner or outside. use good wax to pamper it once a month.
Try to change engine oil on interval of 4k. dont your any other oil except Suzuki atleast in first two years.
Do not go for cheap after market accessories, car will look good without them if you cant go for suzuki official accessories package.
Do not go for tire change, use stock as long as you can drive with them.
Try not to mess with electrical gadgets or any alteration in electrical setup.
If possible get the undercoat rust prevent paint from Suzuki before delivery to avoid rust in future underneath.
Do not confuse your mind about any minor or major problem, if you feel anything abnormal just go to 3S workshop and clear your confusion about the problem.
In the last, if possible, read this forum from the 1st page to last, you will get information about everything about the car's behaviour. good luck.
