No one can give you a serious price on the car without more info. You haven't even mentioned if it is an auto or manual. How do you know it is in good shape? Is the title clear? How many owners? Have you seen the Carfax already? CL cars are caveat emptor so you better do your homework if you have any serious thoughts about getting it. $6,000 is way too low for the average good condition '01 Formula with only 49,000 miles. They should 'normally' be in the $9,000 - $10,000 neighborhood. Red flags should be flying all over the place.
