...some owner's dream?!...not now I'm about to go through the 3rd UK MOT roadworthiness test with not a mile more on the Odo than at the last 2 MOTs!.... This 2000 GTS, sold to me by a very well know LA Viper '''''specialist''''', with the description stored-for-years, very-low-mileage, has an odo reading of 1089 (yes, i shouldn't have bought it.....).

The speedo unit is out at a local well know ex-viper racing service garage, who aren't able to test it with their more modern kit (and they race porsches now)!... Ditto at local Dodge dealer, who can only test back to Gen3.

So...has anyone seen this issue before ?
Is it definite faulty unit - get a new unit?
Can a new unit be got and how does one set the odo??

Please, thank you!
