can anyone suggest me, is it worth it to buy corolla 2008-11 or should I buy Suzuki alto 2019-20 instead
Both are different.One is mid sedan and other is hatch back.Difference of fuel economy is there.Difference of convenience is there.Etc.Hence its all personal choice either you want to drive compact (hatch back) vehicle or Mid Sedan with bigger boot & trunk.
Better to go for a upper model honda city instead.
Since most corollas are run down driven for rent a car purposes.
I think that the corolla would be a better idea, but given its age one should be extra careful when buying. The alto has its advantages such as fuel economy and small size. Try to figure out what is more important to you, and proceed based on that
Alto
