Been there done that... I'd buy the new "high use" parts in black and find used black pieces that aren't seen or used much like the hatch 1/4 panels (can be argued as highly used but you can find some minty ones still). I found some mint black parts for the 4 eye up here in Canada so I'm sure you can find what you need... spending 1500~2000 bucks on reproduction stuff is crazy and at the end of the day you still have cheap plastic imo (not knocking it, just saying)... When you can have a custom upholstered interior for a little more (maybe?)
I'm not against painted interiors if they're done properly (good prep and high quality paint).
