Tip- get a GT3 if you live in a NICE area that has warm weather and a place that DOESN'T HAVE MUCH RAIN (meaning, California, Texas, AZ, NM, maybe florida)... otherwise you guys with GT3's that try and drive them as a every day car are going to wind up spinning out on ur way to work everytime the weather dips or a the road is slick. The GT3 is a race car that can be driven on the street. HOWEVER, it is best to learn how to drive it on the track... it really doesn't drive like a normal porsche.. it's a bit different and takes skill to handle correctly.

The TT is a great everyday driver that is crazy sporty. You can take a TT to the track (but that would be kinda cheating b/c it's AWD). But again, since it's AWD it's PERFECT for any type of weather or driving condition.... the thing is a rock when it comes to driving. However, it does have alot of power--- so you have to make EDUCATED decisions on how hard to push it in certain conditions.

Soooo....

GT3- race car that should be taken to the track and driven hard. HOWEVER, it can be driven as a daily driver--- but LEARN how to drive it. It doesn't react the same as a normal car or porsche does. It's best in DRY- WARM weather.
(the same can be said with the GT2 when it comes out again.) Also, alot of the issues deal with the TIRES-- the tires are made for optimal weather conditions... not winter or anything like that- and this is a SERIOUS thing to keep in mind. If you buy it, make sure you have tires for winter (if you have a winter where you live).

TT- everyday driver, a notch up from the normal 911's. AWD and more power, great fun to drive --- easy to drive on long trips (the gt3 would be a hassle on long trips).
