I saw that article floating on Jalopnik, but just took the time to read it. Very well-written article and I appreciate the depth of David's questions. This is definitely a problem amongst car people that I see all too often, especially with one-on-one conversations where car people.
I have no sympathy to a married man with children and a good career that chose to give in to his obsession in this way....be it BMWs, hookers, drugs. I certainly feel similar urges as a passionate man involved in the car game, but you gotta have balance in your life if you want to make it to your 50s without being a shell of a man.
