At the price point, it can't be beat.
65K miles, one owner, $9K.
The straight six is super smooth and the automatic shifts predictably and powerfully.
The interior is very cush and the entire car has a very solid feel.
It has very strong passing power, but could be faster 0-20.
Also, the auto gets momentarily befuddled when shifting into 1st when coasting at around 5mph when you then hit the gas. If you want a car that is all about performance, the GS300 is not for you.
However, if you want a comfortable ride, nice appointments, a smooth and powerful engine that gets to 110mph pretty fast, its a good choice.
Average 25 mpg on the freeway
Leather interior, heated seats, rock solid feel, moonroof, good brakes, smooth acceleration, not just a dressed up camry like an ES.
