In need of a beater 5 speed, I bought my '90 325i from Craigs List on a whim. Body and paint were not the best, but the interior was straight, the retrofitted ac worked, valves and timing belt had been redone; and it had some iS parts: 14"basketweaves, sport seats, springs, and a 4.10 LSD.
This car is extremely fun around corners and sweeping off ramps. I can bring the rear around in a controlled manner w/ the gas pedal, even at low speeds. The engine is not the smoothest, but steering, shifting, and throttle work together so well- is this the renowned 'German enginnering'?
It's quite the sleeper with its 4 doors. And the insurance is way cheaper than that of the WRX I gave up.
