I'm in the San Francisco Bay Area, and it seems the best deals on the 323/328 are out of Southern California. What are the advantages/disadvantages of buying from a dealer almost 500 miles away to save a couple grand? Is it harder to deal with problems with the car if the dealer is half-way across the state? I guess the local dealer should help one out with any issues whether he/she bought the car from them or not. Any experience/thoughts??
