Then I'll answer, although the car's intended purpose would dictate the answer. Assuming we are talking about the Truck (after all, that's what the thread is about), I'll Say Street Car (my truck) Criteria:
- Run on pump gas
- cruises 55 mph on a 85* day for 1/2 hour without overheating
- drives and races on D.O.T. tires
- Plated and insured, and can go by a cop without being pulled over (EXHAUST!!)
