We recently purchased this car. initially, the speedometer had a small bounce to it, no biggie b/c it was barely noticeable. A couple days ago while on the freeway the speedo went from 70 +/- and began climbing up to 120, then 130+. Now it does this anytime the car is in motion. No matter the speed, the speedo climbs to nearly double actual speed. Yesterday while driving, I attempted to reset the trip meter to see if it was following the same speed as the speedo was showing and the trip meter locked up and does not move... I do hear a small click now when the car is in motion that seems to come from the trip meter.

I've never seen this happen on a car before and am stumped.

Any ideas are much appreciated!

Thanks!
