vipers were owned by people in their mid 20s
Are you kidding me? I could be considered "mid 20s" and know few other people my age who could afford to buy, and more importantly keep, a Viper. In fact, just about everyone I meet is amazed that I own one at such a relatively young age (sure there are a few 18 year olds with them, but daddy buying it for you doesn't count). If Maxim really said that, that's further proof that no one with half a brain should be reading that rag.
Chrysler actually did release the demographic of the average Viper buyer (keep in mind that is new buyer, not owner). It was something like 55 years old, married, income over $250k/yr.
If I had to guess from the boards, I'd say the average owner is in their mid 30s and is either self employed or rather well up in the ranks of whatever they are doing.
