Maybe add cruise control if you don't have it - early cars have the wiring for it so you just need the control stalk, which I think is just over £100 from BMW.
Depending how much you like your wheels you might want to swap them - by the time you sell yours that could even be cost neutral!
Definitely agree with removing the CDV and swapping the gear-knob - the ZHP is so much better.
And a bit over £100 but definitely worth doing is getting your roof motor moved into the boot by one of the guys on here, if it hasn't been done already.
