Boy, Has this ever been a long term love/hate relationship.
There appears to be a lot anger out there surrounding this guy. Most of the knowledge needed to decode and document our cars and the degree of originality (if that's important to you) is out there on the web for free.
Who really needs this guy, unless you need to sell a very high end car and the buyer without some knowledge of what he buying is looking for some assurances.
No one really wants to put up with the long term BS and lack of responsiveness that he seems to probogate.
Fame is fleeting and his actions only hurt him in the long run.
