2000 BMW 3 Series Sedan 328i 4dr Sedan
I have 240,000 miles.
 Check the rear subframe. Have a mechanic check it.  I had some cracks and had to get a plate welded in for reinforcement kit.  At the same time I added a 3.46 open differential out of an automatic 323i.  I have a 5 speed 328i.  I can now pull on s2000's and it's not annoying on the highway.  This car still gets looks with some decent rims (Rial Salerno concave rim).  Other than doing some basic repairs like an alternator and cooling system this car is amazing. Never left me stranded but one time.. the accessory belt broke but that was around 190k and my fault for not replacing it.  Buy this car. Love this car.
