Re-thought my answer. Cars above "most enjoyable".
Best car ever, hands down my '03 Honda Accord. Car now has 225,000 miles on it with one trip to the dealer to replace a leaky rear brake caliper (at 20k). Haven't seen the dealer since. Car still runs perfectly and MPG average has been 32 since new. I log a lot of time in this baby. I know, "least imaginative" but for a daily driver I couldn't ask for more. Will be replaced by a diesel Accord as soon as that model is released.
