I would humbly suggest:
- dash board - Same as body color, for authentic looks as well as lighter dashboards are helpful to toggle in dim light
- front grill - Same as body color
3. doors
4. front bumper
5. roll cage
- front and rear seat covers - Corolla's greenish-beige or grape color in vinyl or leather (as they call it) rather than fabric. A better choice for open vehicles
7. rims
Item 3, 4, 5 & 7, I suggest to try gun-metal grey in matte (not typical gun-metallic. This will give a rustic - rugged look and will go along well with the rest of matte paint job without emphasizing hi-lights and creating contrasts [/I]
All the best.
