That is the first thing I do on ANY new vehicle that enters the stable, other than a tune up if it's needed. New shooz will help you get a feel of how the car behaves and so forth. Also wouldn't hurt to give it a good wash down. I am a fanatic about clean cars, and with a good wash you get to see things up close. You can learn alot about a car by having a good one on one with it.
I have always liked the W126 sedans, they have classic lines and have timeless styling. There are lots of ways that you can style them out. Take your time and be tasteful. Enjoy your new ride, man!!!!!!
