Nobody mentioned that you've done what we've all done and bought yourself OCD.
Welcome to looking out the window regularly, cleaning the car more than you have normally cleaned any car, lotions, potions, polish, tools and treatments for the paintwork, wheels, tyres, leather and interior.
Welcome to being obsessed with squeaks and rattles, engine noises and anything that hints of something that might not be right.
Welcome to staying up late at night trying to work out which part / oil / spark plug / air filter / oil filter / tyres / software etc. would be best and justifying purchases based on Man Maths!
Welcome to looking up part numbers on Real OEM as you want to replace some bit of trim or other ridiculously priced item.
Welcome to checking eBay for parts etc.
Also get used to looking back at the car when you've parked the car for a final look before going about your normal day.
