My experience is over 25 years. Fords-go FAST, terrible brakes and poor performance in cooling. I have fried several. Chevrolet/Buick/Pontiac-good for all around patrol, slow to accelerate, cold performance is sub-par and the door frames need welding to stay attached. Transmissions overheat. Dodge/Plymouth-good for patrol, front ends wear out, rear axles come apart easily, the Slant 6 was THE police engine. 440 Magnums were nice but, they overheated. The best cruiser I ever had was a 1973 AMC Matador with a 401. No, I didn't carry a black powder revolver! LOL
