First of all, welcome to the forum and congratulations on getting a black one - you made the right choice!
When you say fully loaded, how fully loaded do you mean? There’s a load of retrofits and upgrades possible for these cars...
In terms of modifications, I’ve gone with:
E46 coilovers
poly-bushes at the front end
Adjustable camber arms at the rear
Ultraracing bar front and rear
Porsche Boxster front callipers and z4m/e46 m3 csl rotors
Other stuff I’ve added, some of which you may have:
Cruise control
Passenger airbag deactivator
Piano black interior trim (dashboard & center console)
Alcantara steering wheel and a few other pieces of alcantara trim
I’m in the process of retrofitting power folding mirrors
I’ve also done a stereo upgrade (I had the 6 speaker system) with a sub in the rear but kept the one head unit
Don’t forget to do the roof motor relocation to the boot if it’s not already been done, and a stubby aerial - the Peugeot aerial seems to be the common ‘go-to’ for a stubby for just £6 off eBay
I have a thread in the “new members” section (greetings from Bangkok) with more details as some of my updates have occurred, and here’s what mine looks like...
When I bought the car I promised my girlfriend I wasn’t going to modify anything, but you can see what happened
Anyway, hopefully this thread and others can inspire you to modify the car to make it your own
Good luck, and enjoy it
