Hi,
I would look for rust, working of the clutch, excessive smoke, steering. In short: all the things you have to check with every used car. Especially for the Multipl: check the middle front seat if it can still be fold down, working of all the meters on the dash, central locking system is also a weak point. And as last check if the mirrors work the way they should (folding in and out).For the rest it's a really fine car with lots of space :worship:
