I agree with the point, "Fun
I agree with the point, "Fun to drive" is a very subjective term. I took out all three of the cars rated the most fun to drive by consumer reports, as stated above, when shopping and they are fun to drive. I bought a 370Z, because I found it to be the most enjoyable and, "Fun to drive". It has some warts for sure, the biggest of which is road noise, but once past the Z's drawbacks, what you are left with is a pure Sports car, which satisfies the driver in you, and enough power to back it up. With the, "sport" package, ups the fun factor exponentially. (Others will argue, but that is not the point, it's what I found to be the most fun for my $, all the ratings, reports and reviews won't change that). What does have an influence is the, "Reliability" ratings, problem areas reported and safety. Even there, it is subjective as to what is important, how many people are driving Kia's even though their safety rating is sub-par.
"Fun Factor", purely subjective, I have a friend who owns a Smart car and he says it's the most fun he has ever had in a car and he also owns a Challenger R/T, go figure, to each his own.
