A blonde wanted to sell her old car

A blonde wanted to sell her old car,
But nobody wished to buy a car with 250,000 miles on it. so
, she tells her brunette girlfriend at the salon
About her problem
And the brunette suggests
She take the car to a mechanic friend of hers,
Who will turn the meter back by 200,000 miles.

The blonde thinks this is a sound suggestion and does so.

About a month later,
The brunette sees her blonde girlfriend in a store
And says, "did you ever sell your car?"

"no," says the blonde.
"why should i?
it's only got 50,000 miles on it."
