Wtf, there’s no way man . I had a 2012 328i x drive and it only costed me a grand to replace the timing belt ( and local German auto shop) even tho my car had horrendously other problems especially at the age of 19, that car gave me ptsd even though I loved it, worked minimum wage and poured thousands into it. But 7 grand for a timing chain is beyond ridiculous, even obv considering costs are gonna be different for different models.
