1.) You are dealing with an engine (4.0L) which BMW doesn't offer anymore. Year 2000 540i's features a 4.4L engine. It could probably be compensated by your AC chip so you might run as fast as a Year 2000 540i.
2.) People currently are debating whether the M5 will FOLLOW the facelift of the 5 series. But I havn't heard any debate as to whether the 5 series is gonna get a facelift or not. If there is gonna be a new look for the 5 series (as confirmed in www.bmw.co.uk's News Centre), the 1997 model will be dated.
3.) Your 3 year factory warranty is over.
4.) No BMW navigation system (which could be a good thing as the Nav is SOOOOO damn slow in BMW, get yourself an Alpine)
My 2 cents worth.
