I am so happy about my new RX300 I forgot to answer your questions....
To your questions:
1.The logo's come in silver, gold & black. The default is silver, the others are optional. Quite a few people actually take the logo's off, you get a simple but effective custom look.
2.The 2wd will get you a better mileage and has less parts. The 4wd(actually all wheel drive) will be better on ice and snow, something I will never need.
3.There are TSB's that address the problem. You need to ask the dealer about each RX individually. They should have the service record. Follow this link and you can get a list of the TSB's for any yr/make/model. http://www.alldata.com/TSB/yr.html
4.Like any used vehicle, look at the finish and fit, if it looks beat on the outside??? Also, if you go to a dealer ask about and get a CPO certified RX.
