I just acquired a 1958 219 W105 in Maryland USA. It only has 18,000 miles and hasn’t run in almost 20 years. But it is in very good original condition.
First problem. No key. Steering locked.
2) How hard is it to unbolt the ignition key/locking mechanism. It will be a lot easier to get a key made with it out and be able to steer it out of the garage.
