So, I was cruising along the Kalaniana'ole Highway via Google, looking for what was McGarrett's beach house in "Sing a Song of Suspense" (Season 8). I saw it when we were there in 2008/2009, but it appears to be gone, now. Alas! So, I went back the other way. Lo and behold, what did I find, but the Kahala Shell Auto Center, where Jack had his '69 Sedan DeVille serviced! Woo hoo! I've struck gold! Sadly, the station closed recently. From what reviewers on Yelp were saying, the quality of service had declined markedly in the past year or so, and the gas prices were sky high. Service there used to be outstanding! They kept Jack's car running for nearly 30 years!
