Depending on how budget is your budget. Plus your traveling
needs, like family and stuff. To compare the cheapest car in town,
Picanto is much more spacious than Kelisa. But I have know many
family who drive Kelisa, so it is all about how well you handle the
space.
You can give Kia Rio sedan a though, or Chevrolet Aveo. Daihatsu
siron would be 1 of my top choices. Suzuki Swift is 1 comfort ride
with some pack for action. Then there are the all time fav Toyota
Vios and Mistubishi Lancer Manual. Anything above these cars, then
it wouldn't be budget anymore. 
Looks, Space, FC, Power, Comfort. Rank your perferences.
