It's unfortunate that none of the IMSB upgrade solutions provide an externally visible identifier tag.

We do… But sometimes you don't know.. What you don't know. Each of our units is serialized and matched to the VIN of the fitted vehicle along with its engine serial M designation number. This is in the door jamb of every vehicle we have ever retrofitted here at Flat 6 and is also supplied with the IMS Solution kits.

We have also used a similar decal for every standard IMS Retrofit that we've carried out. This decal only comes from a retrofit carried out under our roof, where the IMS Retrofit procedure, tooling and components were pioneered.

If I'd spent a few grand more on a newer model I'd probably decide that the additional investment was worthwhile.

If you knew what I know, that statement might not have been made.
