1994 Mercedes-Benz E-Class

1994 Mercedes E320
Runs and Drives for about 20-30 minutes before if starts cutting out
I bought the car about a year ago. It sat a few months because of a worn flex disc. Once swapped the thing ran great and was smooth on the highway. The propblem that I've had now for about 2 months is what feels like a misfire/cylinder cut out when it gets warm. It'll drive fine anywhere from 15 to 35 minutes before it starts misbehaving. I've swapped out the coils, spark plugs, wires in an attempt to chase the issue to no avail. Currently it's parked at my job where I only drive it to lunch here and there.
Besides that,
the roof sags,
the seats are ripped,
driver door panel slightly coming off
original radio still works but needs antenna receiver motherboard
i've replaced the worn 2 front tires to match the rear 2.
I love the car and loved the sporty feel but I just don't have the time or energy right now and would hate to just have it sit
I do recommend towing once purchased.
Thanks for viewing my ad
