tbh is all about personal preference. so long you can understand how things work (cars = liability, loan repayments, etc. ) and most importantly able to accept it.

can also refer to pc, which i believe if you know me [or can just click my profile lol] you would know how much money i've wasted on a pc that depreciates [in ways] faster than a car, the only main difference is the scale of money

that said, my car is almost 12 years already if that mattered. i plan to buy an over 100k car, but thats once i manage to get a comfortable pay level first. and i do plan to drive the car over 7 or even 10 years, of course, things may change if i settle down with my own family and what not, however atm i'm single (inb4 2" jokes) and i have no tie downs/heavy commitments (eg: having a kid lol)

as for the tire bit, one should be changing all 4, and thats assuming they arent idiots who dont do proper tire rotations to even out tire wear (hence front/rear drive etc should not matter on wear)

and considering "youngsters" we're talking about, they usually are idiots who knows jack about proper maintenance and most importantly just feed off family wealth
