spoke to chuck tator of tators dodge..unfortunately you guys who have vipers after 98 can only estimate build # because of prowler, viper mix up..on your door you can get born on date of build..sorry..
The year does not matter here..... Nobody can figure their build number based on the VIN. The only run of Viper made in VIN sequence were the GT-2's. All other Vipers are sequenced in groups of six, so they could be shipped together in a single truck to dealers that are close to each other. The VINs are assigned at the time of order, but since groups were built together based on shipping locations, the cars are not built in VIN order.
As an example, last week a fellow asked me how he could be buying a 2002 ACR with a VIN of 825 when the first ACR VIN is listed as 832 on the IVR
Build Info page. That's because the VIN on the first ACR that went down the line was 832..... 825 was built later.....
