First of all, check all the fluids.
The bonnet pull is a round metal pull, hidden under the dash, behind the steering column.
The dipstick for the oil (on the lhs of the engine)
The radiator for the coolant
The brake fluid. (this is under the carpet where the driver sits, you should undo a cap with LOCKHEED on. Fluid should be just below the filler neck)
If you have done all this, try and see if the engine turns over by the starter motor, even better with the handle.
If all that is smooth, and not stuck, start the engine. Depending oin the year this is either by turning the key, then pulling the rh pull-switch.
The later cars just use the key as in a modern car.
You may need to use the choke when starting, that's the pull with 'C' on.
Then very carefully drive it, and test the brakes.
Of course you need to be insured, MOTd and taxed
