Mercedes diesel cars euro 6. Avoid purchasing one. I have 2, one from new and one used. Continually having NOx sensor issues with engine warning light on and fix is about 800 quid (and they have multiple sensors). I love MB cars and have had several over the last 20 plus years, however these 2018 onwards ones spend more time being fixed than in use. I cannot recommend them and would warn others to stay away from them (unless you like spending money in the dealership).
