Considering you are 6.1, and your budget is 7 lakhs max, here are a few suggestions
Avoid Mehran. You will get arthritis in your knees!!
You will fit in santro as it has good head room but the seating position is like sitting on a dining table chair.
Cuore, it is surprisingly roomy for the front passengers. I kept one for 7 years. I am not tall (5,8) but a friend of mine (6,2) borrowed the car for a day and was full of praises after returning it. He himself had a CL9
Cultus previous gen will fit you just fine.
Baleno will fit you just fine.
What else will fit your budget? Corollas and civic from 1995-2000. All will fit you just fine.
