I purchased 2nd hand Open Corsa 1.6GLS (Petrol) three months back for only 90K year 2000 model well maintained, I got it serviced repaired the broke mirror and repainted the bumpers(looks like new now) which cost me around 12K. I am super happy with my decision it’s the steady car with good pickup(A true German engineering car).
I get millage around 11-12 kmplin city and 15-16 on highway(without AC) I also have Santro Xing which gives me millage of 10-11 kmpl in city and 14-15on highway(with AC).
So I recommend peoples to think for these big cars as an option before going to small cars. You will really enjoy and feel the difference in big car:-)
