I have the chance to buy a really pretty 300E from a friend. It has about 180Kmiles we think. the odometer was changed at some point but a Carfax type report helps us to get close on the miles. I am used to BMWs and would probably stay away from a 5 or 7 series with these kinds of miles. What would you be concerned with if you were interested in this car? The interior is great. There is a small oil leak, very minor at the cylinder head gasket. What would be a range of good prices for this car? Thanks.
