1985 560sel

A close friend of mine just bought Saturday a 1985 560SEL at an auction. I am sort of cunfused though. I thought the 560SEL's started in 1986. Don't they also have a 5.6 liter engine? His is a 5.0. He got it for $500. and it runs and drives perfect. Needs paint and seats are a little crackly. Everything works even A/C. When we ran the vin # it came up as a 2001 some other model. The bumbers are half the size as our other W126's. Would this be a Euro model??
