Smart blonde

Old joke but I don't think it's been posted before.

A blonde walks into a bank in London and asks to see the manager.
She says she's going to Hong Kong on business for two weeks and needs to borrow £5,000.

The manager says the bank will need some kind of security for the loan, so the blonde hands over the keys to a new Ferrari.

The car is parked on the street in front of the bank, she has the title and everything checks out. The bank agrees to accept the car as collateral for the loan.

The manager and the tellers all enjoy a good laugh at the blonde for using a £200,000 Ferrari as collateral against a £5,000 loan. An employee of the bank then proceeds to drive the Ferrari into the bank's underground garage and parks it there.

Two weeks later, the blonde returns, repays the £5,000 and the interest, which comes to £17.41.

The manager says, 'Miss, we are very happy to have had your business, and this transaction has worked out very nicely, but we are a little puzzled.
While you were away, we checked you out and found that you are a millionairess. What puzzles us is, why would you bother to borrow £5,000?'

The blonde replies...'Where else in central London can I park my car for two weeks for only £17.41 and expect it to be there when I return?'
