Just bought my K5 10 days ago and got a few things done to it. I plan on keeping it pretty simple and not doing much else. I got the roof and pillars wrapped in gloss black vinyl as well as a chrome delete in the same vinyl. I had the dealer tint the windows to 5% around the entire car and added some 19" wheels. The specifics are TSW Sebring 19x8.5 5-114.30 with a +40mm offset and tires are Yokohama Advan Sport A/S+ 245/40r/19.
