There's about a 5 mph difference between my car's ('95 LS auto) reading and my wife's car ('02 Corolla). I'm assuming that's not normal, so I'm also assuming one of us will need to get this fixed. If it turns out to be me, how much can I expect a fix like this to cost?

 

Figure out how far off it is and live with it. That's free. You really can't do anything else.

 

Has the tire size been changed from the stock ones on either cars? Tire size in height will cause a change in how fast your car is really going.

 

my car's lowered and it's about 6 mph off....i've learned to live with it

 

Honda speedometers are notoriously inaccurate anyway, live with it

 

when i cross the line in the 1/4 mile, my spedo says 110 but im really trapping at 102. but like said before, different tires throw it off and the higher you go, the higher off it will get. just learn to live with it, its not that big of a deal

 

I think the 5mph is true for all hondas & acuras. Same 5mph gap when driving with my dad's Benz and gf's Mazda. I'm all stock...

 

Well then, I won't worry about it. Thanks, everyone!!
