If you're expecting a huge change on the facelifted BMW 5-series, you're in for a disappointment like the fans of the Mercedes E-Class were when they saw the new E-Class.
Headlight, tailight, and small lower fascia changes will happen on the outside and some small interior modifications are in store.
The biggest change will be in the engine department as the 335i motor will make its debut as a 535i.
There will also be some option package/pricing changes and new offerings like night vision.
Finally, look for a few color changes when the car is readied for the 07/07.5 timeframe.
