They're both great cars but maintenance might be abit higher than what you're used to if you've owned their competitors such as Toyota Vios and Honda City, if the additional maintenance bill isn't an issue (also because these brands sometimes give free maintenance for 3 years) one of the biggest headache is service center. Even here in KL there are only a handful of Ford 3S, so which brand is fine but look for which one was the 3S or service center nearest to you for convenience.
1997 Proton Wira 1.8 - it looks to have a decent CD player, but nowadays you can always get a cheap China brand player that can play all sorts of media even USB. The 1.8EXI's were quite sort after because it has the best bits that other Wira's don't have such as ABS brakes, 4AT gearbox, good power for highway cruising and decent fuel consumption. Because of their limited run there was a majority of them which were actually CKD Mitsubishi's. This model is the cheapest to maintain, you can find stuff for it everywhere.
Livina uses a normal slushbox automatic gearbox while.
Latio, Livina and X-Gear share a similar gearbox with different gearing ratio's.
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.
