cup of tea or a test drive?

I've been keeping
my life running
like an old car
that's half made
of junk-yard parts

The clock's busted
and the fender's rusted
but my character engine
can be safely trusted

I've made it through mountains;
I've made it through woods;
I've made it through cities
bustling with hoods

I've done some things wrong
but dented steel's still strong:
an older model, sure,
but centuries go in circles
as it were

Might I interest you
in a cup of tea
or a test drive?
