Interesting. I lived in LA up until 2007 (Westwood, in particular) and commuted by bus to Santa Monica via Wilshire Blvd. Back then, even that was a PITA. Glad to hear your friends have had a better go of it.
I'm now working in tech, so I'm able to work from home and avoid commuting (thank God). I'm tentatively planning to move to East Hollywood, where my community (improv comedy folks) mostly congregates. My goal is to live within spitting distance of Barnsdall Art Park (near where The Clubhouse venue is), or, failing that, the UCB Theater on Franklin Ave. I figure there will be a Vons or Ralphs somewhere nearby, and I guess I could Uber for everything else. That said, I'm a huge foodie and having a car would allow me to explore the city in a way that public transportation just wouldn't.
I was planning to buy a classic car like an old 70's-era Ford Bronco / F150, Jeep Grand Wagoneer, or Chevy Silverado since I'm not a huge fan of modern auto aesthetics, and that kinda lends itself more toward a private-party transaction anyway. I feel like, as long as I find an apartment with gated garage parking, that should reduce most (but not all) of the risk, right?
