The 1999 GS 400 was just the second installment of the vehicle, so there were no changes from the 1998 model-year offering. The car retained its powerful, 4.0-liter, V8 engine., , That engine produced 300 horsepower and offered acceleration from zero to 60 miles per hour in 6 seconds. Later, 4.3-liter versions of the GS 400 did not improve significantly on those numbers., , "You cant fix perfection," wrote one owner when asked what improvements he'd like to see on the GS 400. Safety-conscious drivers were a bit put off by the rear-wheel drive, but performance-minded driving enthusiasts would not have accepted the GS 400 any other way., , WE DON'T MAKE THE PROFITS OTHERS DO, WE DON'T HAVE TOO!!, , NEED FINANCING? , , GO TO...., , WWW.MYNORTHTEXASAUTOS.COM, , 100% GUARANTEED APPROVAL!!!, , ALL INCOME ACCEPTED!!!, , ALL TYPES OF CREDIT WELCOME!!!
