You got an absolutely amazing deal on this. Holy shit. This would go for $2-3k EASILY in my area on Facebook marketplace. The only cars that you can get for under 2 grand around here have either don’t run at all or have plentiful issues/one major problem, or are sketchy af with every light on the dash on.

I get that it sucks, but it isn’t the dealerships fault. They can’t do anything for you if your out of warranty. You need to open up a case with Mazda customer support if you really feel like you deserve compensation for it
