The GS300 or the IS 300, which one should l get ?

id rather get GS300 because it is bigger than is 300. l have lexus GS 430.

IS300 because is it smaller and faster than the GS, and uses less fuel.

both r using the same engine but slight different HP (GS300 has 10 more, 225hp). still u will feel IS faster, quicker steering feel & better handling (std 17'' rim) while GS300 using 16'' as standard. If u have kids, need more space, comfort then GS is always a good choice to think about, but if u r young or u want to feel like that young, IS gives what u want (style, feel, speed, luxury, etc).overall they r both lexus which is so reliable & really confuse u which one to get when u consider to buy a car which can last longer & less problem.

is 300,cheaper,seems faster

If your looking for something a little smaller and much more of a sports car go with the IS 300, l personally think that the 2004 IS looks better than the 2004 GS, but if you are looking for something roomier and not so sporty go with the GS.

The GS will generally be more expensive than the IS. But both are great cars, it just depends on what your looking for (roomy vs. not roomy, lower price, and sporty or not).

l would get the GS 300. It is more sporty, expensive, luxurious, and roomier.
