The 4th generation Legacy was well received by the press and public alike, and sold in decent numbers from 2005 to 2009. Even with a high MSRP (for a Subaru) a significant number were sold with manual gearboxes.
The 2.5 GT badge on the back means this Legacy is powered by a 2.5 liter version of the EJ25 flat-4 borrowed from the USDM Impreza WRX STI. The Legacy version uses a smaller turbo and different tuning to push out 250 horsepower and 250 ft-lbs of torque. The turbo wagon even maintains a 2700 lb towing capacity should you need to augment the ample interior storage capacity.
The Legacy uses the same hard plastics you will find in most Japanese economy cars from the early-mid oughts, but the cloth seats will look nicer longer than leather found in premium cars. The only place you might find some wear is on the touch surfaces (steering wheel, shifter, window buttons), but otherwise the 10 year old interior should look like new.
