Datasystem turbo timer

[savini101]

So as the title says im interested in the data system turbo timer. its old but i like it because it fits s bodies so well.

it just slots into your spare dash spot and clips straight into your ignition. plug and play.

I know they are rare but no idea how rare, is there any point looking? also, does anyone know what they are worth?

any advice is helpful at this stage
