What are the differences between 2004 Toyota Sienna CE and XLE trims.

I have been looking for buying a used minivan. After doing some research on both Honda Odyssey and Toyota Sienna, I decided to buy Sienna.I personally do not like to buy a used car. I am not the kind of person who liked to change car models frequently. I liked to buy a new car and stick to it until it dies. However, certain circumstances prohibiting me to buy a new car. First of all I do not have enough money to avoid financing, Second I have to pay way more for car insurance as I have to have full coverage for the car that is financed.

Now Toyota sienna comes with a few trims like: CE, LE, XLE, XLE LIMITED. A few of these trims often come with AWD and 8 Passenger seating option. I really don't know what are the exact differences between CE ,LE,XLE other than a few extra features.(Purpose of this post is, my reader may give me more information by the comments and I will learn more). So far The things that I learnt are:
CE:
This is the base model. Which has same engine and other mechanical components. However the internal looks is different, the climate controls it has is slightly different than XLE as CE has knobs instead of a single press button for various vent control. Beside you see only cloth seats by default. I am not sure if they all are equipped with power sliding doors and power rear Hatch lift gate.
LE:
This is the upgraded model from CE, that's all I know. I saw that it has same dashboard and controls like CE, only thing I know it may come with 8 passengers and awd if you add it. If you know any more please let me know by your comments.
XLE: It is the Trim that include many features by default, like leather seats, and button controled vent on dash. It has power rear Hatch lift gate. It may include some other options like sun roof/moon roof (LIMITED) , a overhead Entertainment system,parking sensors and many other option depending on what limited package is added. This is all I know about this three trims. I am still searching online to sort out exact differences. Threrefore, It will be highly appreciated, if you have more information and share those here through your comments. Thanks for reading.

Update: I have found the following differences between Base Model CE and upgraded model XLE: (collected from http://www.motortrend.com , common items are not shown)
