On the one hand, fiddling with your car may bring back memories of your grandfather or uncle working in the garage and induce a sense of nostalgia rather than a desire to put on a work overall. Especially since, after all, none of us are a match for mechanics employed by the best car companies, so by trying do it ourselves, we might do more harm than good.
There are many different car owners. Some buy a car just to commute to various places; others treat their vehicle like their friend, or even like their lover. They care about it, nurture it, calibrate and refine even the smallest details. Regardless of what type of driver you are, surely you will always be interested in improving the performance of your car and correctly tuning it.
