Pst office in the morning.

Just had a read myself, the clause to euro 4 is the registered date of the vehicle

Light goods vehicles (TC39)

Registered on or after 1 March 2001 (not over 3,500kg revenue weight).

12 months rate £185.00
6 months rate £101.75

Euro 4 light goods vehicles (TC36)

Registered between 1 March 2003 and 31 December 2006 only (not over 3,500kg revenue weight).

12 months rate £125.00
6 months rate £68.75

Euro 5 light goods vehicles (TC36)

Registered between 1 January 2009 and 31 December 2010 only (not over 3,500kg revenue weight).

12 months rate £125.00
6 months rate £68.75

Me can not see for looking (must of been wishing to much)Never works

So it makes no difference euro 3 or 4 mind we could be paying £400 like the rest of the 4x4
