Thats the sort of attitude from a kid that does the engine change and then kills someone because he forgot to do the brakes as well. He will then be complaining that HIS life is ruined.

Insurance companies are now sie to this and will screw you over big time, foprgetting to delcare wheels is diffrent to fortgetting to declare an engine change, also the DVLA and police are now taking action against this sort of thing.
