I think some agencies are just afraid of change and others are just waiting to see how well they hold up. I know we put 'em through hell sometimes. The CV's hold up fairly good considering the abuse they get. I've always tried to be easy on my car because I've always had a take home car and it had to last about 4 years or so before I got another one. Some people don't care though. I saw one guy get a brand new CV and had to have new tires and brakes at 10,000 miles. The boss almost went ape s**t.
