Which is more reliable, the 2011 Ford Crown Victoria or the 1993 Volvo 240?

When the Volvo was brand new it was more reliable than the Ford when it was brand new. Right now they are both unreliable without knowing a lot more about their condition.

None of the above! The Crown Vic is likely to be a retired police car or taxi cab, while the Volvo is 25 years old. BOTH cars are probably used up and should be headed to the scrap yard.
