Well I bought my 525i about 3 month ago it is my first car. The car broke down on me about 2 weeks ago and I just barely got another job so I can fix it. I love this car, greatest car I've ever drove. The crank position sensor went but she's got a lot of miles. I put some upgrades into her (Aftermarket clutch, Cold air intake and straight pipes). This car is so fast with the upgrades, but the engine does need to be rebuilt.
Speed, Handling, Comfort and the girls dig it.
Tad bit more horsepower. A power chip works great though.
