Hello everyone! Just bought my first Bonneville a few days ago for a daily driver (2008 Silvy with the 6.0 and 4x4 doesnt exactly get great mileage in stop and go traffic =D) and gotta say I love the car! It will definitely stay on as my project vehicle.

Love the site, lots of great info!

Yeah, I like the white and blue a lot. Though the only other cars i have seen it on are usually police interceptor impala's.

Thanks for the listing 00Beast, I entirely forgot to get a PCV Valve. It does have a nice new K&N Air Filter, goodyear belt, and a fuel filter that I've yet to put on it. Got a few other things to do yet. Runs beautifully though.

Just make sure you get the o-ring sealed on the PCV, otherwise the car will have a huge vacuum leak and run poorly.

I'm here to help!
