Hey all, so I've given up my search for a C30, as I can't find a good example. So I'm leaning towards an S40 instead.
I found a clean, low mileage example that was serviced a couple of weeks ago prior to sale.
If you look at the dipstick, the oil kind of smears everywhere and isn't 'built up' like I'm used to seeing on previous cars. The dipstick's hard to take out and insert, so maybe it was just rubbing against the tube, I'm not sure. There's what appears to be rust in the tube and some milky substance under the oil cap. It's not currently dropping oil or leaking coolant, even thought there's white, mottled spots marks on the metal underneath.
What do you think? The oil is a bit yellow and transparent, but I guess that's normal.
The oil marks in the engine bay is just where it dripped off the dipstick while taking the photo.
