Here's a link to a photo blog I did on ffcars.com. A group of 4 of us drove from Seattle to LA and back last year. We drove down the Pacific Coast Highway, did Mulholland Drive, and a track day at Buttonwillow. I ended up blowing a head gasket near Sacramento on the way back up. We had planned a second track day at Thunderhill but the engine blew right as were arrived at the track the night before. It had been having issues for a while. I ended up having to tow it home.
Bottom line is it was one of the best adventures I've ever had. Sure things may go wrong (two out of the 4 of us ended up having to be towed home), but that's half the adventure - nothing ventured, nothing gained.
250 to 350 miles a day is easy - 500 would be pushing it, but doable for a day if need be. Anything longer would be punishment.

We're leaving Seattle at the end of June this year for another trip down to Norcal.
