2001 S500

I purchased a a 2001 S500 Designo about 5 months ago. Spring is coming and I would like to have a unique look but, I don't know anything about wheels, tires, etc. I see so many posts about staggered sizes and other wheel size issues. I definitely want to keep the same ride! What wheels are very nice that can replace the stock rims that came on the car without changing the wheel or tire sizes? Also, I am in Chicago, does anyone have a recomendation for service? Any other subtle changes you could recommend would be greatly appreciated. Please send photos if you have done them to the same kind of car.

Thanks Much!
