I don't know about that... Life is about doing what you enjoy, be it change or more of the same. I still have my second car, '74 'Cuda which I bought in 1988 when my first car, a '70 Swinger, got smashed. I'd probably still have IT if it hadn't been t-boned at high speed by a Benz 560.
As far as performance, I think it's possible to have "enough" performance without compromising drivability and reliability. I base that exclusively on the fact that, as drivability goes down, so does the street fun factor, so you've gotta find the happy medium for you.
