Generally Japanese imports are very good. Thousands of used imports are imported into New Zealand every year. From typical Japanese cars which are available new in our market (Suzuki Swift), to European cars and exclusive JDM models. Like the Toyota Century, or Toyota MKX.
They care for their cars (cosmetically) to a high standard, especially the interiors. Most imports are immaculate.
There is a good chance that parts of the car, especially bumpers have been repainted. Either because of damage, or just to keep the car looking good from stone chip damage etc. The resprays are often quite easy to spot. Colour matching not quite right, rough paint finishes, or masking tape lines around window trim seals and the like. I would say the red car has had a full respray. But I could be wrong. For instance the image of the rear badges, on the bumper there is a rectangle of different colour. It may have just have had some old Japanese dealer sticker down there, or some other sticker and all it needs is a buff. Or perhaps they masked around the sticker, painted it, and since arriving in the country the sticker was removed.
Of course, what 18+ year old car has not had a little bit of a respray.
Generally not much rust with Japanese imports. Unless it was damaged. Cars from Singapore are usually associated with damp and electrical failures due to tropical humidity. How true that is, is hard to know. Singapore cars usually come with English dash and owners manual.
Car service history is always patchy, apparently this one has service history. Owners manuals are often missing.
Some Japanese cars are imported into Japan in LHD configuration, to make it more a 'prestigious' and 'authentic' foreign car.
The cars often have annoying toll road readers installed which make noises when you start the car. They can be removed, of course. Other car makes (Volvo) often have displays and the like displayed in Japanese characters, which require conversion. The Alfa probably does not.
They have a small space in the passenger footwell for a flare. These are often missing however.
