I just purchased an 06 IS350 with 81k and I love it. I think I know what model I have, but maybe somebody can help me. I wanted the most basic option package since the factory nav system is so old now. I do miss the heated seats though. This thing is full of blank switches, which is what I wanted. Fewer things to go wrong!




Options:
Heated/Vented Seats - No
Nav - No
18" Wheels: Yes
Woodgrain: No
Sunroof: Yes
Power Steering Column: No
Memory Seats: No

I am thinking I have the base model, but wouldn't that come with 17" wheels?

 

You have the base trim car. Although 18" wheels were part of the luxury and sport packages, they were also offered as a stand-alone option for base and premium trim models.

Check out the 2IS buyers guide in the FAQ sticky at the top of this forum where you'll find this information and more.
