my 94 2.0 automatic altima gets 7km/li city hehe * 145hp, can't complain about a car that handles well, fast, very comfy, and clean interior design... at the same price of a friggin lousy 1.3XL Corolla with no power (literally) and bare as hell...
If you can stand the LRT look :P
but based on your options, I'd stick to 1600s... Doesn't matter kung Toyota/Honda/Nissan/Mitsu, 2.0 and higher cars are expensive to maintain relatively and parts are not as easy to get...
Sentra parts are verrrrrrrry easy to find hehe, and the fact that Nissan dealers (casa) always have good sales sa parts, you'll end up buying OEM stuff all the time without spending a fortune...
