I used to have a 99 Tahoe 4X4 LT 5.7 with the pick-up tail gate. It was silver, although the dealer called it Plenthium, and I put Smittybuilt side bars on it. I don't like the side flares or running boards. The running boards are the only thing I hate about my 2012 Yukon SLE 5.3. They just collect all sorts of road debris & dirt. What a pain in the ass! The only other thing was the window shields. They allowed me to lower my windows a tad to let fresh air in when parked, usually under a tree. I tried to find a pic of her but alas no more. Basically, I like to keep my rides simple and not too much flare or fancy stuff. Makes it attractive, but not so much as to attract thieves. If it looks too good they want it or know someone that does.
As for the front bumper I would look around a scrap yard first, but if you're into the steel tubular bumpers they are a good choice too. I kept my Tahoe original with the shock absorbing mounts. Came in handy quite a few times, especially when I was teaching my daughter to drive. Her mother was a completely different story. But surf the web or even this forum as I've seen some really hot, elegant, sophisticated rides here. Good luck & welcome to TY Forum!
