I highly recommend the E46 330xi. I have a 2003 as well, and I love it! I've put about 123,000 miles on it and it still drives like new. It's only had one problem with it that rendered it un-driveable, and that was the ignition coils arching about 75000 miles ago. However, that was in the morning. By the afternoon, it had been flatbedded to the dealer 45 miles away, and I picked it up at 4:30. It does fairly well in the snow, especially with proper snow tires. Good gas mileage. It's not screamingly fast, but it's got plenty of power. Very comfortable on long drives. I do not have the xenons, but I wish I did. Anyways, go for it and good luck!
