Interesting thread to justify having one in the stable. Because topics in the LS460 forums are repetitive I’ll add mine to this discussion. Numbers wise, the LS460 and IS350 are very close but I wouldn’t say the experience is similar.

Reading some replies I cant help but relate because I have SPDS Aisin with M mode and a modded V8 attached to it. With some F DNA, GSF sized Brembo’s and 4400lbs to move around, the combination is likely 80-90% of the thrill behind any early ISF with an open differential. For me the transmission is why I’ll keep this one for a long time. Up front may not be Yamaha tuned but the combination with 8 cylinders is the deciding factor.

As for the quote above, with key shared F performance parts, for a flagship the LS460 Sport/F Sport is just that if you need more interior space. The balance between flagship comfort and switching over to M/Sport mode is night and day makes you want to rack up mileage. Yes a LS460 is an irrational daily driver, I’ve never regreted a single mile.

 

I have been very close to selling my is350 and getting an ls460 for more family space. I appreciate your input. What year is yours?

 

Mine is a 2011. 2010-12 was known as the SZ in Japan had the E diff. The facelifted 2013-17 got the F Sport branding and the Torsen. All the space you could want in a sedan and the opportunity to paddle row gears and have rev matching downshifts. Even better when you toss the factory air for Fortune Auto colovers.

 

I may eventually go this route, but I’ll need to come up with some cash for that upgrade. My wife decided to reduce her income, so all the sudden I’m paying off her car early lol.

I think the ISF is the superior sedan in the Lexus Line up, but honestly the only mistake (IMO) is the is250. The 350, F, GS, and LS are all excellent cars. It just comes down to one’s needs.

 

I see your point and agree. All things aside, I tend to value cars more that can be used for its intended purpose for the greatest amount of the time. For instance, my ISC I can use use everyday and use it up to 9/10th of its full capability. My other cars, tend to be weekenders/track/offroading and on these SoCal roads, I'd be lucky to get 4-5/10th of the capability out of them. That makes them torturous to drive. On balance then, for me, I'd say I'd keep my ISC because on almost every situation, I'd get the most return on investment dollar based on how I drive here.

 

That's funny, for a short while I was considering the 2010-2012 LS Sport. I had an 08 LS460L Executive Package and it just didn't "feel" right/sporty enough for me so ultimately got a 2010 750i M Sport (glad I sold it before things started going south bad! But goodness, that thing was capable). I always missed that LS for never skipping a beat (except the rear pass soft close motor failed twice and I wasn't too happy with the air suspension tuning, it always felt like there was a secondary vibration in the chassis at certain speeds).

Have you had the melting dashboard issue? I like this generation of the LS though because of the touch screen, I can't stand the trackpad thing on the 13-17(?) LS. I LOVE having a touch screen. If I find a mint condition 2012 LS Sport, I might have to give it a go though. I do wish it was a hair faster however.

 

How many stock IS350 are doing 1/4mile in 13.3 sec? I had 2008 IS350 with Fsport exhaust sway bar suspension bone stock consistent 13.5 with two 13.4 on day with perfect DA and track prep was spot on. That was 2 yrs of ownership in Nov 0f 2010 I got my 2011 ISF and never look back. Instead of bench racing you should take both cars out on same day drive them like you stole them them see if theres differences.
