It's a 68 plate.
50/50 is a bit of a dice roll from a reliability perspective. 
That would be Ingenium diesel, and per around 2019/2020, the older chains, which are the single most common issue with that engine - not helped by the stupid stated service interval of something like 20k, which is ridiculous for a diesel, and especially a chain driven one.
For anyone else looking, check for chain rattle at start up, if it has any, walk away - popping on the newer chains will need around £2k. Chains aside, I thing most people think the 2l Ingenium diesel is a brilliant engine, and is powerful, refined, and spectacularly economical.
