Some people are a wee bit different than most. I suppose this guy is completely different than most (here). As for your advice
hey,littlecobra .. noted. But please take note yourself that I'm a Police Officer who not only can 'read' BS from people and do so everyday - I also keep my Car and my home under lock/key/alarm system/Glock 22/Mosberg 500/attack Doberman.
If you can get by the locks. Disable the alarm. Distract the Dog. Start the car. And, do so without getting shot by me .... heck, take it - it's insured.
This guy was a little flaky, granted, but he didn't come across as a total BS-er.
