Inspira would be the better overall car if you do not mind the badge. Sylphy nowadays concern me with their CVT gearbox issues, consider a Latio instead.

2011 Nissan X-Gear - you might also want to consider this car, it is the shorter 5 seater version of the Livina, as a new car it is the cheapest C-segment you can buy in the market, as a used car it is still quite an interesting bargain. It uses an older engine and gearbox combination (no CVT) thus better reliability and also cost of maintenance (as older tech is always cheaper). It has a unique crossover look if you like that sort of thing it is big and spacious for long distance but the engine might not be giving out enough ponies as overtaking is very limited once you pass 120kmh.

2010 Toyota Altis 1.8E - it is quite true Toyota makes boring and uninspiring cars but when you need something which is cheap to maintain, fulfills its duties and is reliable then it is one of the go to brands for most people. This Altis model lost out alot of market share because it was pitted against the Honda Civic FD1 & FD2 which were selling like hotcakes but that doesn't make it a bad car as eventhough it didn't get the critical mass like Civic did but because Toyota recycled almost everything from the previous model of the Altis into this one except the looks thus spare parts can be shared so many the whole range cheap to maintain.
2010 Nissan Latio - previously I would have put the Sylphy above the Latio because it is a much more elegant value buy c-segment car, however finding out the issues with Sylphy can be quite serious and expensive especially for the inexperience it is better to choose the Latio as it's engine and gearbox are the standard type not fancy but very reliable and cheap to maintain. Looks wise no doubt it takes some getting used to, however the higher roof gives it an airy feel on the inside. Maintenance and replacement parts aren't going to break the bank either, and it is quite hard to find all these qualities in a c-segment car at this price which is only 5 years old. The are both hatchback/sedan variants they're pretty much the same except the sedan has one model with a 1800cc engine, the rest are all 1600cc engines.

why not consider 2nd hand Preve or Suprima?
