Disappointed with performance

I have BEAT Diesel car and it crossed almost 75000 KM running , But now I have started facing lot of problem
1] Engine is consuming oil , I have to replace it every 5000 KM
2] though I have new battery Engine starting problem has started .
3] Pickup has started drooping very badly.
4] Very high maintenance cost as I have paid more than 2 lacks in servicing in 5 years
5] Service stations lack good technicians to identify problem, they only know how to quote high servicing bill by replacing parts and loot money specially in Bangalore . GM have very limited servicing stations
6] All parts are not easily available outside so have to rely on those service stations for servicing who are there for looting money.
7] GM India has very pathetic customer service ,they don't work seriously on your complaints
I have to get rid of this car but again in Market revaluation value is extremely less ,
I will recommend not to buy this car due bad technical service and high maintenance cost
