My NUMBER ONE Warning That You Should Heed

There are a number of things that can break on an old car but this one will really leave your stranded!

From my own experience and from hearing from lots of other's experiences I can not stress enough - DO NOT NEGLECT YOUR IGNITION TUMBLER AND STEERING LOCK ASSEMBLY! If your key is starting to "stick" or "catch" in the tumbler then you shoud replace it before it will not turn and leave you stranded!
