I'm considering the GS300 for my next car. Specifically a used 1998-2002...I've owned several Honda's and Acura's over the years that have been great. I like the GS300 for a more sport-luxury type vehicle to be used on long road trips, not necessarily a daily driver. Are there any known problems and what should I look for when buying a used GS300? Any advice will be appreciated. Thanks.
