Who is BS'ing who?

lets not forget about those cars were the speedo reads 5 mph fast. that is an easy area to pick up a few mpg, ha ha. How many cars have the right number tooth speedo gear--about as many that has all 4 tires at the right air pressure. It can be done but you have to do your homework. One number of teeth off and the speedo reads 2.5 miles different, two numbers its 5. Pretty good for selling the car--seems faster than it really is, look how fast the speedo climbs when you floor it, lol
