In the end you just have to compare vehicles and get what you want. You'll almost always get a better value from a used vehicle because you aren't taking the new car depreciation hit, so it's almost an unfair comparison. By the time the Toyota/Scion/Subaru is out you'll probably be able to pick up a base 370z or 2011 Mustang GT for mid-low 20s, since I've seen them as low as 25-26k already. The first gen Genesis Coupe will probably drop its value some when the new model hits too. And if you don't care about weight, you can already get a first gen CTS-V for under 20k. Add a few grand for an aftermarket warranty if you're afraid of something breaking, and you're set till 100k.
I've owned two brand new cars though, and there is a really good feeling associated with having a brand new vehicle.
