I say, just look at what you have in your surroundings..?
Do you have a Car of pure indian origin which is acceptable? NO
Do you have a mobile phone of pure indian origin (Design not manufactured)? NO
Heck do you even name a car engine which is of pure indian design...? NO
Err what kind of curveball is this

Do you have a Car of pure indian origin which is acceptable? - Depends on the definition of acceptable to some a BMW M3 is unacceptable

Do you have a mobile phone of pure indian origin (Design not manufactured)? There are two - Samsung Z1/Z3. Both are designed (physical and software), built and sold in India. I can personally confirm this since I know the design teams.
Heck do you even name a car engine which is of pure indian design...? The recent Tata turbo petrol 1.2 in the bolt is completely designed/built in India AFAIK.
