My definition of a street car means that in the event something happened to the car you generally drive everyday you could, without hesitation, drive your "street car" as its replacement - even for extended period of time. As said, some people are more tolerable than others. My Daily Driven fox (for 3 years) has no A/C, H/C/I, heavy clutch, no rear seat, no radio, 3:73s, dumped exhaust without cats, no wipers and skinnies on the front - but none of this bothers me enough to make me hesitate to drive it under any circumstances.
