you won't get that kind of long life from a WRX. the engine is different, and is created for torque (speed). You don't buy them for long life, you buy them for fun. You could expect about half the lifetime for a WRX as you would an Outback or regular Impreza.
All of the new cars have 'Continuously Variable Tranismissions'. I really hate this new development. Yes, they get better gas mileage. But, the way they drive is . . well . . icky, IMO. When you put your foot on the accelerator, there is a 'lag' before the car kickes in and moves forward. In the old fashioned type of transmission, the correlation between how much pressure you put on the gas pedal, and what kind of response you get is a perfect 1: 1. The CVT goes more like 1/4, then 1/2, then 1.5~! So, it is slow to respond, then sort of 'jumps' forward to make up for the lag.
I find this diconcerting when I am pulling into traffic and I want to know exactly when and how my car will accelerate. a lag of any kind is dangerous if you are timing things too close.
However, I will have to get used to it, as pretty much all new cars have this type of transmission, and my old Honda Accord, 'Rosebud is her name, is going to be gifted to the son (the Outback is being put to pasture). So, I will have to get a new car.
