My passion for bmw started from my father. He had a 735i 1991, metalic blue. He used it for about 10 years and then gifted it to me when I was old enough to drive. Dad even taught me the basics of how to take care of it before driving, giving me a printed instruction manual on how to care for "his baby". His list included washing at least once a week, a general "lights work, gear work" type of maintenance once a month, making sure to almost never park it under the sun, and if I do to cover it with a
portable car cover that should always be stored in the boot, to clean the intertior of the car once a week as well. And the guy checked too, to make sure I was following his manual.
Unfortunately, the car fully broke down, engine, wires, and all and was just too much to fix, so sold it for a m3 2008. Dad was upset about it more than I was.
