Thanks Kumar sir and Ramky sir for your responses on this one..
You are right Ramky sir, based on what you explained about the route, Rajkot >> Shirdi >> Bangalore really needs a good SUV and endurance.. However, I felt Palio did perform well, little beyond my expectations...again, I'm not a right guy for comparision as I have very little driving experiance and almost 99% is with my Palio
I've reached Bangalore yesterday evening and read these responses today only. I had decided to take the normal route Rajkot >> Ahmedabad >> Mumbai >> Bangalore
Later when I was close to tarapur chokdi, I decided to bypass Ahmedabad and Baroda as well and took Tarapur >> Borsad >> Bharuch route.. that was a mixture of good,okay and bad patches again with two lane roads almost all the time..
I felt I spent lot of time by while hoping to avoid the 150 KMs patch between Baroda-Surat which is being worked on at present...coundnt avoid Bharuch > Surat part of that patch with diversions though...
spent one night in Mumbai and another on NH8 a guest house (not a good experiance) close to Goa intersection (after Nipani). Overall it was a very good experiance,, I should plan more such trips but in a little organized fashion..
I shall wait for next opportunity and make Bangalore >> Shirdi >> Singnapur >> Bangalore.
Thanks again..
