Depende sa budget nya, but better go for something newer (2009 or younger). The 2009-2013 City/Jazz GE 1.5L offers a good balance of space, utility, and fuel efficiency. The previous generation Vios is another option but I have never been a fan of its looks and its dashboard layout. If you want a compact, then the Civic FD (2006-2011) or Altis will be among the best options. If you want something that's performance-oriented and thrifty on fuel, go for the Ford Focus TDCi Powershift (2009-2012) but they say CRDi engines are a bit costlier to maintain compared to gas engines.
90s to 2000, walang matipid na AT diyan. Swerte ka na maka-8 km/L in city driving.
From 2000-2013 IMO best buy would be the Altis 1.6V. Almost the same efficiency as a 1.3 or 1.5 AT subcompact but with more power, space, and a more upscale image.
