The changes which I've made are - Elongated boot and hood (to give a more grand look), increased headspace (by raising the roof a bit), an additional row of seats in the back (that makes it a 7 seater), 22-inch wheels in smoky black color along with low profile tires, and an overall satin black paint job.
For the interiors, I chose a pearl white and crystal black color scheme along with a custom mandala pattern accent on the dashboard, gearbox casing, and door panels.
