I had a 2003 MCS, and my dad still has (and loves!) his 2005 MCS.
For me, I think it would be a lousy car for LA. Regardless of which suspension option you have, the short wheelbase will kill you over the expansion joints and crumbly freeways. You may get a better ride with 16" wheels vs 17". I also found it very much prone to rattles. That being said, when driven like a sports car or on twisty roads it is tons of fun!
