I always ask to rent an economy, compact car.
"The cheapest one you've got!" I say.
Well, when my son and I went to rent wheels in Seattle over our spring break trip, the cheapest car they had left was a cherry red Mustang sports car.
"Whoah!" my 7-year-old son said. "How fast does it go mommy?"
We never found out how fast it goes as I'm a cautious slow driver, but we did have a lot of fun cruising Seattle in our red hot car. Better yet, Budget charged us the economy, compact price.
