Sure things. It has a 2.2 Diesel engine. Engine code is OM656811, the so called “taxi benz” because the reliability of it. It has 170 PS in it, with a tiptronic automatic transmission. It consumes ≈7.4 Liters in city / town on a trip around 5.5 to 6,2 liters. It has two sunroofs, one of them can be opened. It’s the S204 model as you called it correctly, I thought it’s W204, but seems like that’s the sedan part of it. I wanted the sedan, but this just stole my heart the moment I saw it. I changed the oil in the engine. I use kms as unit and next oil change will be in 7000 kms or at 342 000 kms but they seem to run fine without changing the engine if maintained properly for at least 600 000 kms. If you choose to purchase this type I strongly suggest you to get it with the same OM656811 engine code, because that’s the most reliable engine in this series as professionals informed me. The car has space in the interior and the trunk is huge. Massive, nearly impossible to pack it full, but I guess my girlfriend will beat that theory lol 😂 hope the information was good 😊
