I have a 96 W210 E320 M104 inline 6 engine with 165K miles on it.
The car looks and runs great. I still enjoy driving it.
Everything is in good condition and no major problem except the paint on the hood is starting to show its age.
There are no wiring harness problems but I recently noticed some oil leaked near the front of the engine (dreaded head gasket problem). This leak is not fresh, it just looks like there is some dust on a previous leak. Been monitoring it but no significant level drops on the dipstick.
Just did a rough estimate that I may have between $4000 - $6000 of future repairs/maintenance on this car in the next 2-4 years.
Who knows, it may be more.
I am not a mechanic so I can only do the basics of car maintenance (oil changes, brakes, spark plugs, etc.) and everything else, I would have to send to the dealer or indy.
Currently the car is valued from $6,000 - $9,000. Which means, I can save $10K-$15K if I just sell now and get a new $30,000 vehicle.
I would like to keep this car and drive it as a daily driving car but I have been recently thinking about the future expenditures and wonder is it really worth it?

I look up to those on this board that have much higher mileage than I and ultimately I would like to get 300,000 miles on this car.

Please let me know your thoughts.
