I got my G400 about 4 months ago and I love it. It was a 99 with 64k miles, spoiler, nakamichi sound system. The car is an absolute blast, and makes for a very reliable and sound purchase. The ride is very smooth. Days before I got the car I drove my friends Mercedes Benz 430 sedan, no comparison, I find that the lexus surpasses it in nearly every case, especally on the road which is truly important in my book.
Prepare to become accostomed to what my friend like to call the slingshot effect. Push down on the gas and you'll feel the V8 spring to life and gently slide your bum into the back of the seat. 60mph wooshes by and before you know it your easly surpassing 80. In my opinion a car should relialbe, safe, fun to drive and the Gs400 has all of those traits (especially the fun to drive ) Good luck with your new car and hope this helps ;) ~ Ignition
