This happens way too often
My project car (pfp) used to be my grandparents, they took it to a sketchy mechanic and guess what! The oil (even though it was supposed to be 1000kms old) was black, my dad also took his car there a couple of times and then though “yep, they are sketch.”
Dealerships are also scummy places, if you buy a car from “2000” or “2010” it is very likely it would be from 1999 or 2009, also what happened with my car, dealership labeled it as 2000 meanwhile it was made in July of 1999.
People only want money now. The governments are corrupt, that’s why they make all of these regulations on cars/washing machine etc, not because it is better but because they want money. Take e cars for example, seems like they are good for the environment right? Nope, e cars have lithium which is horrible for the environment also the co2 footprint 1 car makes is huge, also need a new e car every 8 years as the batteries die. Bring back old washers and start using LPG cars!
