Tires/Rim selection for 330i 2002

Just wanted to get opinions before plunggin $35k on new car. I just ordered a new 330i but I am not happy with the stock rims. They look good but I know they are a pain to clean and they always look dirty.

The dealer is just giving me the option to change to the 325i sport package rims (style 96), which are 8" wide instead of 7" like the stock rims (style 73) or changing to run flat tires with rim style 98 (comes with tire pressure monitor). Both options cost me $300.00.

My thinking is if I go with the 325i sport rims I get a wider/lower profile tire...but the car will look like a 325 instead of a 330. On the other hand if I change to the run flats I get the same tire size, loose the spare and gain a tire pressure monitor. I don't know where and how is the tire pressure monitor mounted inside the car. Have not been able to see one in a car or a picture. I am also interested in anyone with the run flat tires comments. How is the ride? Any changes in driving dinamics? I know this option also changes spare to space saver tire...wonder if the little weight difference changes anything.

I test drove a 330i with regular rims. What a car!!! I don't want any changes to it.

Thanks in advance for opinions.

I am getting a 330Ci with the 18" wheels. I am still not so sure about the wheels. I need to see them in real life in day light (I looked at them on a 330Cic at nigth).

Anyhow I would say get what you like most, so that later you will not think "I shoulda, I coulda..."
