I wouldn't advice any of these vehicles for daily use, but I know a few who still use these as daily runners. They're reliable vehicles, but considering the age (15+ years) and the abuse they have gone through you're likely to experience repairs and will have to spend a considerable amount of time in the garages once in a while. Parts are easily available. If you would like to settle with one of these, AE110 > FB15 > BJ5P > N16.
Its personal preference in the end that matters. Do take a trust-able mechanic with you have the vehicle inspected thoroughly, almost all vehicles of this age are clocked so don't bother with the mileage.
The N16 and FB15 do have some suspension issues, you may have to replace certain suspension related parts every 20-40k kms, nothing major though. Please do search the forum and you will find a lot of information on these vehicles as they have been discussed extensively.
How many kms do you plan on running every month? Doesn't a newer hatchback suit you?
If you're into hatchbacks: Viva Elite, Passo, Kelisa, Swift are some options you can consider.
