The hobbyist/enthusiast aspect of owning multiple cars is a legitimate reason. "Because I can" is also legitimate". To me, multiple car ownership becomes questionable when it results in living beyond one's means to the point of causing an unpleasant life. I.E., having to work an unreasonable amount (giving up other important life factors) to be able to pay the additional insurance, maintenance costs, etc. surrounding that luxury. I just don't get it - living a "rat race" lifestyle in order to have possessions beyond one's means, sacrificing other quality of life factors (family, fishing, & fun, etc.). I also prefer the idea of keeping fewer, better condition cars vs. more cars that require LOTS of upkeep. Those that LOVE working on cars are exempt!
