2006 Subaru Impreza Sedan WRX Limited 4dr Sedan AWD w/Off-Black Int. (2.5L 4cyl Turbo 5M)
I suggest if you ever get the opportunity to buy this car and it is within your grasp, do it. It is a really reliable car so fun to drive. Keep in mind however it can take a little getting used to if you're tall.

I purchased my 2006 Impreza 2.5i almost a year ago now. So far the car has remained reliable and cheap to maintain. I had a minor problem with the exhaust plumbing that was fixed under warranty, but other than that just oil changes and an alignment. The car has enough power to have spirited acceleration. The turn-in is sharp and precise; good steering feel, shifter is smooth and fluid, seats offer good support. The interior is a good driver's environment with excellent touch points. The car handles very well on both dry and wet pavement.
The AWD was hugely important in my purchase decision. It offers traction advantages that simply can't be had from FF, FR, or even MR vehicles. I also like the engine packaging that results in a lower CG and better F/R mass distribution. The suspension is also nice and stiff stock.
60/40 seating. Stickier tires. A tad more rear roll stiffness to decrease understeer and fight body roll with the new tires. A hair more power (just a hair because it's only a 2.5i), perhaps from something as simple as a K&N drop in filter. Other than those simple fixes I'm a happy camper.

This is my 4th Subaru (1 outback, 1 legacy, 1WRX, and this vehicle), and this is the best one yet. It handles perfectly, and the gas mileage is unbelievable. I use this vehicle as a first responder car and I have beaten even the police cruisers to calls. There is not a single thing I would improve on the vehicle.
