Car needs re mot'ing when recorded as cat c.
I insured mine first
Mot'd it
Vic checked it
Tax'd it
When taxing it at local dvla office also had to apply for the V5.
As for a cat c recorded car being worth 50% or less of it's value than a non recorded car.
B*llocks.
Every cat c I've bought and sold I've never struggled to sell and have always got strong money for.
Cat c don't means it's f*cked lol.
