Do shops still sabotage cars for profit?

Have you ever got a price for a heater core install?

I can't say from personal experience but it's not very cheap. Labor is what costs not the part.

They're not cheap, but they are a lot of work and i don't think the payoff is worth the amount of work that has to go into it. Ford trucks for instance; you have to remove the entire dash along with the steering column. It's like they built the entire truck around the heater core.

Most dishonest people aren't too bright.
