We're always impressed to hear about "survivor" cars, found in barns or dusty garages in all-original condition with extremely low miles. However, it's just as cool to see vehicles at the opposite end of the spectrum. Some classic cars are daily-driven year after year, decade after decade, racking up miles and soldiering on with incredible reliability. Such is the case for this 1969 Dodge Dart GT. Its slant-6 engine has covered nearly 430,000 miles without a single rebuild.
