Toyota Passo.
What to Check Before Buying.

The Toyota Passo is a compact city car sold primarily in Japan and various export markets, though rarely seen on UK roads. Built on proven Toyota mechanicals and sharing components with the Daihatsu Boo (later Sirion), it gained a reputation for efficiency and straightforward urban driving. Most UK examples are imports, so verifying service history and checking for rust on older models becomes especially important. Buyers should confirm the car has been properly registered and meets UK type approval standards.

The average used car has 3+ known model faults the seller won't mention.
