All coupes come with sport suspension. Sport package gets you nicer seats, I believe.
I love my '04 325ci. It's plenty quick, comfortable, reliable, and even gets good gas mileage on the freeway.
I searched for years for the right car, and finally got one with only 36k on the odo. I cannot emphasize enough that low mileage, good maintanance records and a clean PPI are more important than color, options, engine size, etc. Best of luck, and have fun!
