E39 BMW 523i for starters the car was extremely underpowered it was a 2.3 liter inline six in a 5 series. The schockabsorber were gone and wen you hit a bump you would be feeling it for the next 5 minutes which was the best part cause the travel this car had was unbelievable I know this car is not bad but the one i drove was just in horrible condition I still own a bmw e34 530i with a little 3 liter V8
