The GTI, for us, is a near perfect vehicle. I get close to 40 mpg highway cruising at 80. It has plenty of torque in 6th gear to climb hills and accelerate on freeways without downshifting. There is room in the back for Costco, and the rear seat is adequate. And it handles well, they dialed out the understeer for the most part. The only issue I've had is replacing two tires from road damage. The Caddy was a bit large for the city.
And it really had no more usable room.
