This website aims to assist individuals with traffic infringements. However, the OP's situation could be more challenging as he failed to update his V5 and consequently received numerous PCNs. Unfortunately, appealing these PCNs is not an option since the TEC will reject them due to his failure to update his V5.
The OP is now burdened with a substantial debt that is beyond his means to pay, invoking a sense of empathy in the audience.
Both the council and the bailiffs are in a difficult position, attempting to collect money or assets that the OP simply does not have.
While this website offers extensive expertise on traffic penalties, it is evident that there is a lack of practical advice on bailiff enforcement. The OP, in his quest for actionable information, has found a potential solution here.
There is no need for a hypothetical debate about the car being towed by bailiffs, as that falls outside the scope of this website, which focuses on motoring advice rather than specialised enforcement guidance.
