WE ALL WANTED TO BE RACE CAR DRIVERS WHEN WE WERE YOUNGER, BUT
THERE’S A COMMON MISCONCEPTION THAT YOU’VE EITHER GOT TO BE BORN

CARS THAT ARE SIGNIFICANTLY LESS EXPENSIVE THAN SOME OF THE ONES YOU'D
FIND AT A DEALERSHIP. YES, THEY’LL BE SLOWER, BUT WHEN YOU’RE JUST
STARTING OUT, SLOWER IS A GOOD THING. IT FORCES YOU TO SQUEEZE EVERY
OUNCE OF PERFORMANCE OUT OF THE CAR.
