l am going to bre getting a new car and l can not decide which one the 2006 Subaru WRX or the 2006 Subaru Legacy Gt Limited which is better and FASTER and in your opinion wich looks better?

l think the WRX looks cooler

Looks go to the Legacy GT.
Speed goes to the WRX ever so slightly (14.3 1/4 vs 14.3, 5.6 0-60 vs 5.7).
LGT is slightly more powerful off the lot (250 hp vs 230 hp).
LGT is slightly more refined, and has the better interior.
Both are relatively easy to modify, but the WRX is slightly easier.
WRX gets a couple more mpg.

l have a WRX, but my next vehicle will be a LGT, if that says anything.

Without doubt the new Legacy is a superb car. It is not quite as mad as the WRX but it is very fast and if you alter the ECU later on speed and acceleration beats the standard WRX. Chipping will cost about £250.
l think the WRX is too dated.

It depends on what you're looking for in a car..
WRX is a smaller rally inspired sports sedan with less weight than a Legacy.
The Legacy is a heavier, smaller turbo, less comfortable ride.
Styling is different for both cars, l personaly like the looks of the Legacy, very classy sexy looking ride.
Where the WRX has a meaner look to it, hate the grille.
Speed, the WRX is going to be faster than the Legacy, even though it puts out less power, the tuning is way different.

the WRX on both. it is lighter, and the 1/4 mile time is .4 sec faster.

Looks and speed IMO go to the rex.

l like how the Legacy looks.
