Here is one from a US member (GammaLex):

i have over 100k , and the only problem i had was a shimmy in the steering which the fixed after i went lemon on them. the car is great , but it needs the l tuned steering ecu and the l tuned shocks and springs and the racing sways and stut tower bars to go around a curve w/o riding like a buick. additionally the car sounds alot better with a kn ram air set up. i thik it goes faster too, but most people say it has no hp effect. if it doesnt have factory hids just find one that does dont try to add them,to much mony and effort . the milage is about 20mpg overall, im sure u could do better , but it is so much fun to run this car, why bother. a little hint to go faster , turn off ac , turn off traction contol,put in manual and shift to 2 and don't let go

wow, you guys must drive slow

I managed 20 MPG on the highway last week and wanted to throw a bash for that accomplishment! I usually get about (rounded off on my NAV screen) 14 city/18 highway on a regular basis.

I have mygs4 for 3 months and it is the worst MPG among all lexus I had!
my IS300 full tank can drive 260miles ave
my 3 sc4 can drive 280 city, 450 highway ave
my ls430 can drive 350 city and over 500 highway
my lx470 can drive 300 city
but my gs4 only drives about 220miles and it need a refill!!!! ohh well, I have srt+ecu, hks exhaust and fat setup on tires... but shouldn;t it be better???

that's weird, coz' my gs4 is having pretty much the same gas mileage as my sc430 and is300. of course with teh tc and lsd i am getting a bit less gas mileage now, but that doesn't usually happen unless i drive aggressively
