How to Test Drive a BMW 525
1. Test drive the vehicle when the engine is cold, if possible. While it idles, get out and look at the exhaust pipe. White smoke should not come out of the exhaust pipe. If you see white smoke, there is something amiss with the engine.
2. Drive the car on a bumpy stretch of road, if possible. The suspension should feel stable, and the shocks should not bounce excessively. Vague steering and an overly-soft suspension may mean that shocks need to be replaced, which can be a costly job. On the freeway, the car should track straight, even if you take your hands off the wheel. If the car wanders, the alignment may be bad, or bushings in the suspension may be worn out and needing replacement.
3. Apply the brakes and pay attention to how the car behaves. The brake pedal should not pulse or vibrate, and the pedal should feel firm. If the pedal vibrates and shakes, the brakes may need to be replaced.
4. Drive the BMW on a variety of roads, including city streets with slow traffic, faster freeway driving, as well as a winding road, if possible. This will give you a better idea of whether you like the way the car performs. Generally, BMWs are sporty cars and thus feel different than driving a comparable car from a different company such as Lexus, for example.
5. Inspect the car as part of the test drive. Open and close all doors, trunk and hood to make sure everything operates as it should. Also, check all electronic features (air conditioning, power windows, sunroof, etc.) to verify that these systems work. Closely inspect the paint and body for defects or signs of collision damage.
