What decade produced the best cars, in your opinion?

.....and currently, I've got a craving for 1930s cars. The cars of that decade were very nice, even the "cheap" models were nice looking....

Some early 2000s cars were decent...they didn't yet have the horrible "bubble" appearance....

One thing I really hate about 2010s cars are the awful black grills. Just awful. 

I love boxy cars too. Very underrated in my opinion. 

Even the ordinary family cars of the 1930s were quite nice. For example, Plymouth was a "low-end" brand yet still produced lovely cars like this:

I guess if I had to draw a fine line, it would be roughly 1964 to 1974 American cars.

Plenty of power, emissions controls hadn't completely ruined the power and efficiency of the engines, and they were fairly easy to maintain. While maintenance isn't much of an issue on today's cars (outside of changing the oil/transmission fluid and maybe changing spark plugs once in the life of a car), it was very easy to do the things required to keep a car from that era running. I also think the era produced some of the cleanest and best looking cars. While I like the 1950's styling excesses, most of the cars just weren't engineered very well. In the 1960's you started getting better and more reliable automatic transmissions (GM's Turbo Hydramatic 400, Chrysler Torqueflite, etc.), disc brakes, ball joint type front suspensions, front and rear sway bars, seat belts, collapsible steering columns (very important in a head on collision), etc. The engineering and safety improvements alone made this era's cars still able to perform well on today's freeways unlike previous decades. Starting in 1975, cataylic converters came on the scene as well as other emissions and fuel savings devices which made cars much less reliable. In the 1980's computers started making the cars more reliable but at the same time styling was beginning to suffer and cars all started looking alike. Badge engineering didn't help, especially with regards to the American Big 3.
