No, not everyone has these problems selecting a new car. A lot of people impulse-buy based on looks, or R&T's comparison chart, or something similar. A lot of people let their company, their friends, or their SO make the choice. Some people are always looking, so they have a good idea of what they seek, before they actually start shopping.
You want new, you want sporty but conservative, but also something your parents wouldn't be seen in (unless it's the passenger seat), right?
You can use the comparison charts to eliminate a lot of vehicles, but you really can't tell anything about a car until you've driven it. Every new car smells/feels good and drives nicely. All you can really tell about a new car drive is how good the visibility is, and how well the interior ergonomics suit you. You can eliminate some cars based upon just this information, but not all.
Suggestion for the cars still on your list after your visits to the dealers: get a "rental rider" for your current insurance (mine was $19.95/yr {YMMV} and covers any damage or other issue with regards to a rental car, including "down time" while the rental is being repaired {no cc "insurance" or comprehensive covers this!}...You have to ask your agent for it, and not all insurance companies have it available, but most do); then make a list of your top 12 remaining prospects. If you have friends who own cars on your list, see if they'll let you borrow them for a day, otherwise go to your friendly neighborhood Rent a Wreck and rent 1-2yo models of your top 12 (or as close as you can get to them). You will get much more valid input from living with the car for a day, then you will from any test drive!
See what the car is like after the new car smell has worn off and it has been beaten up by potholes and curbs. Park it under a hose and see if the sunroof or convertible top leaks (or the doors or windows), drive the he!! out of it and see if it handles like you want. Go for a road trip and see if the seat gets uncomfortable, if the controls are intuitive (and to your liking), if you get a reaction from passers-by, etc. Take it down a bumpy road and see if it rattles, or if the suspension and steering have minds of their own. Play with every thing that moves (knobs, switches, seats, etc.), and see if they deteriorate with age, throw a couple friends in the back seat, see if they fit...remember, to you, this is a two year prospect, but your family is going to be looking at, and riding in it for much longer.
For a ~$200 "research" investment (not much, compared to what you're going to spend), you'll gain an incredible insight into which cars you'd really like, and you'll know which you'd really rather not drive again. Most of all, be patient because you are spending a lot of money on something you'll have to live with for a while...
