Hello sir, I purchased an LS460SE about 2weeks ago and can tell you that they’re a really special car indeed!
I was lucky in the fact that my neighbours A short walk away are a local Toyota Lexus sales and repair, they had looked after the car for the last 10 years for an elderly gentleman and he had only clock up 20,000 miles in that time and serviced it every year, so the car has only done 39,000, it’s an awesome v8 and a pleasure to drive. I have put a Race-chip xlr throttle chip on, to improve lag and throttle response( beware of R+ mode) as the Ls becomes a real beast from the east! In Sport mode it’s really great, without the chip or in the neutral setting there is slight delay in the throttle or the feeling of having to press the throttle Quite hard for response. There is a bit of wind noise at high speed, but nothing to worry about if just cruising. I don’t think the control arms are an issue, probably the Americans doing to many donuts! I asked what oil they had used and they said the 5w30, so I think I’m going to get them to put the liqui moly 0w20 in with the ceratec ceramic coating, should work a bit better as the climate will allow a thinner oil. Mine has the 18 inch allows so not sure if I’m going to change for the 19inch alloys that the car your looking at has. The only other thing is I’m considering is a ever so slightly louder growl from the exhaust, I might be sounding like a boy racer but I’m really not! Just like the small tweaks to get a bigger smile as I drive the ss enterprise! One thing I will say Is that it’s not the filling up it’s the speed at which the fuel gauge goes down! But worth every penny me thinks! The Japanese really do make a masterpiece of a drive. Good luck with your purchase
