Save your money and wait if you want an isf. If you want a family car you won't race every day from 0-60 in 10 foot go with the gs. If you got the money then separate yourself and go with the gsf. If you don't care about all that, get a corvette or some other fast cars.

 

I Traded my 2011 ISF for 13 GS350Fsport when it first came out..I liked its interior (Cabernet) with all the tech but few days later i realized i made a huge mistake...Missed the whole ISF Feel.

Went back to the same dealer just a week later to trade it back for the ISF, i was lucky enough and did not loose substantial amount.

My point is, don't just buy the car based on everyone reviews...Drive both cars back to back and make a decision.

To be honest, Gas mileage on the F isn't bad at all (Not too far off from GS350)

IS-F resale will also be higher (Due to rarity)

If you don't need the extra room and 12.3" Nav Screen...I would go with an F without a doubt.

 

i had a 2013 gs350 fsport, really nice car but id go with the ISF, its a better weekend car IMO

 

Speed and thrill = IS-F. Comfort and technology = GS350-F. Your choice.

 

Imwouldmgo with the gs.. I like bigger cars. The is is too cramped in my opinion and it is a dated design... If I was 10 years younger I prob would have said is-f but there is no where you can go 100+ mph anymore with all the traffic cameras light cameras and cops.. A fast car like that would also get in trouble..

 

What did OP end up doing? I'm curious. I'm in the same exact predicament. I've been looking for the right 2011 ISF, but I literally cannot find one and it's been over a month. I'm resorting to a 14 rwd gs350 f. 3 years later...has anyone's thought changed? All I can say is the value of the ISF is definitely holding, but at the same time it's a lot more outdated at this current time.

 

I actually sold my GS F-Sport for a 2011 ISF. TBH the 4GS didn't do it for me and I had 2 3GS also. Interior design may be a bit dated on the ISF but I definitely prefer the touch screen 100% over the mouse.

 

As some one who has an ISF and a GS350 F sport what he said is about as accurate as you can get lol.

Old post I know but my 2 cents.

 

Lol maybe in Cali they are (which is a huge Lexus state, IMHO) but everywhere else? Outside of a dealership or tuning shops, I've only ever seen a few other 350 F-sports. . Hell GS (gs-anything) in general are relatively rare in new england. Compare with something like BMW 5 series where you see crap-tons of those all the time up here.

I have owned a 2008 ISF (3 years) and a 2011 ISF (3.5 years) and now a 2013 GS350 for ~15 months. The GS350 is a nonFSport/non Luxury trim, no ML, only has ventilated/heated seats + rear sunshade, so it is pretty basic.

Given the choice between a used ISF and a new/barely used GS350 fully loaded, I would say go with the ISF. The rear leg room in the GS350 is not that much larger than the ISF, the only thing that is larger is the trunk space in the GS.
The power and cornering abilities in the ISF alone are reasons enough to go with it instead of the GS350. Yeah, the GS350 can hold its own, but that extra performance and exclusivity of the ISF is worth the ownership.

The ML in the both ISF's weren't that good, but neither are the ML and base audios in the GS350. I did listen to the ML in another GS350 and have heard much better in other cars with "upgraded" audio packages, so Toyota/Lexus audio systems aren't really that good overall if you're looking into good sound quality.

If I could do it again 15months ago, I would have looked into a 2012-2014 ISF instead of the GS350. But I do put on around 2000 miles a month these days and it would be a waste to drive that much on the ISF even if they are bulletproof at 200k+ miles, so the GS350 fits the bill for now.... on a separate and off topic note... the 2018 Ford Mustang GT is looking pretty good now specs and price wise....hahahhahahaa
