Bare with me folks....

Do all the RX300's have the same thread measurement, for lugnuts?

Also, I've noticed some RX's have the rear wing lifted up and some don't, on my 99 I don't think it moves. I'm assuming it's the way it is.

Lastly, Anyone know what the scheduled service is for the 99 RX300, example: what's done on a 60k service etc?
Just curious

 

Don't know about the lug nuts... I imagine they're the same.
As for the rear spoiler. It doesn't move - it was redesigned in 2000. 1999 was the only model year where the main "wing" of the spoiler was parallel to the glass. From 2000 on, it's straight out parallel to the ground.
If you register to access the Owners section of the lexus.com website, you can download electronic copies of the owners' manual and the maintenance schedule.

 

Fantastic

Is there a way to download previous history off of this vehicle?

 

Your Lexus dealer can access a Lexus database of all warranty work that was done on the car.

If the previous owner used a dealer for maintenance AND both that dealer and your dealer participate in regional or national database for tracking maintenance work, then your dealer can also pull up full maintenance records. Lexus doesn't maintain such a system, but it seems that many dealers participate in a third-party database system like that.

 

Exactly, I went to my local dealer yesterday and they pulled up the entire history of the vehicle.
It says 30k performed, 60k performed etc etc.
It also say Non OEM accessories installed throughout, wonder if there's a way of knowing what was done?

 

"Non OEM Accessories" could mean that the dealer installed some accessories before the car was originally sold. Things like the roof rack crossbars, wheel locks, floor mats, and sometimes the rear spoiler are not installed at the factory, but are instead called "Port Installed Options", or PIO. PIO's are installed after the car gets off the boat (or train, from Canada) but before the window sticker is printed and the car is allocated to a dealer.
It's possible that you have accessories like this that weren't PIO, so the dealer added them once they got the car.
I was really surprised by this one time when I had my RX 330 in under warranty to repair foam falling out from underneath the spoiler. Before the service department did the job, they checked the computer to make sure it was factory. If it wasn't, they would have forced me to go back to the dealer where I bought the car for warranty repairs. I had no idea that you could get an RX 330 without the spoiler, but I guess technically it's possible.
