Hi Cullen
Micras are prone to rotting at the rear sills (a search on a previous post of mine shows pics).
A car that age check all over for rot.
Service items are cheap as well as brake components (pad/discs/calipers/shoes)
Sunroofs can leak. There is a drain pipe from the appature that end in the sills, filling the inner sills with water. These can be re-routed to drain externally.
Top of the range models SE+ come with electric windows,Aircon parking sensors.
Good luck in your quest for a suitable car.
