how much it needed?
Hello, I'm not sure exactly what you mean by your question, but I am guessing you might be asking about fuel efficiency. It is hard to judge the efficiency of these older muscle cars. No official EPA records were kept. I can assure you they are not the most efficient vehicles in the world. Current mileage would depend on how well the car was kept and on any restorations or modifications made. I hope this answers your question. If not, try another one =) CarGrrl
