I would suggest a Skoda Octavia since one of your requirements is safety. And the Skoda's tank like build quality is unmatched by the corolla and the the Optra. I agree with speedbuster that the Octavia does have a slightly cramped rear seat compared to the Corolla or the Optra, but not by much. I think the Skoda Octavia 1.9TDI Rider is just about perfect for you. Its a very refined and silent diesel, so your fuel bills will be kept in check and since its a Rider, it does not have the appeal that the Elegance and L&K have, so IMHO, i feel its a perfect match for you

, and if you don't like the diesel, there is also the petrol which is an equally good car.
And BTW, in no way are any of these cars going to take anymore than 5 passengers comfortably. If you need to fit in more people in one car, i strongly suggest you look at SUV's. Since you find the Scorpio and the Innova to be too big for your liking, i feel you should seriously look at Cheverolet Tavera, I own one and believe me its a real good car at that price.
Cheers
