What it concludes

Buying an older BMW 3 Series like the E46 330xi for under $1,100 provides an affordable platform for racing, autocross, and drifting despite mechanical and cosmetic issues.
Unplugging a failing mass air flow sensor forces the car computer to use backup air-fuel ratio tables, confirming the sensor is the cause of idle issues and lean codes like P0171.
A stuck BMW sunroof can be manually closed by removing the interior panel and turning the sunroof motor with a T25 Torx bit.
Selling non-safety interior parts like the radio and wood trim offsets budget race car penalties when exceeding the $500 car price limit.
