I have 97 E 320 with 97000 miles.Last week after small accident(animal ) light damage(plastic parts),next day noticed oil marks under my car in the garage.After driving all day can smell oil,went to local MB dealer(Lincoln/Nebraska).I was told after inspection,that I have several problems,what need to be fixed and it will be cost $ 7000(!)-head,head gasket etc.I cant' believe this price.Anyone with this problem from the past?Oil leak problem will cost me half the price what I paid for this vehicle?I am not a mechanic,but this is too much,I think.Any advice or recommendation?
