oooh, gotcha. My advice is to look thru the picture thread and see some cars w the rims on. I think seeing rims in the showroom is not a great way of telling the look on the car. Few shops stock a wheel that fits a w204, they are crazy offsets and only will fit a new Eclass too, other wheels fit many cars and are stocked by bigger rim shops. As far as install, any rim shop can swap your sensors and get you tires or stock the size you need. On exhaust, anyone that does custom exhaust or at least has a hydraulic tubing bender/expander will do the job. Its a mercedes, but the exhaust is run of the mill like any other luxury car, nothing special really. The quad tip mod is pretty straight forward, most meineke mufflers and chain places can easily bend and add a tip. Ive put 3 different exhaust setups on my current C, and I wouldnt do the add a tip, I would get magnaflows and custom tip those, that way you can weld the stock ones up in 5 min and trade in or sell down the road, plus the aftermarkets sound way better
