Wait until you start chargin people half price just cos you cant stand to see the car drive past you in that state everyday.
Wait until you walk into a Lamborghini showroom and when the owner of the showroom asks you what you think the only thing you can say is.... Why does it have swirls? Why is that rim not polished inside? Why did you leave the arches dirty? and then conclude in telling him the car wont sell.
Wait until you log into the internet and the first thing you do is check what car has been detailed by what person on detailing world.
Wait until you cant sleep at night because there is a Audi A4 3.0 litre Quattro outside your hostel and all you can think about is the car getting stolen and how exactly you will remove that one single scratch causing you to only fall asleep at 2 in the morning.
Or you could just wait until your parents stop giving you pocket money cos you spend it on cleaning products
I could go on forever
