Previous sedan was Jaguar xj-40. This GS 300 is much better, more reliable, and far fewer maintenance issues. Running 17" wheels w/Toyo Proxes. May go to 18" wheels next. Yes, could use more back-seat legroom. Off like a shot with a tap of the accelerator. Corners great and tracks steady. Have 130,000 miles and still get 26-28 highway mpg. Will buy a GS 350 next. Gotta love 'em.
