Yes kezo you would think it would save a bit of admin time to pay the lump sum but I’m OK with waiting. Oh and I wrote the wrong figure above on the GCP it should have read £350 not £320. I wasn’t sure about the 4 year payment as I see a lot of stuff about 3 and 5 years payments but not seen anything of late about the man in the middle 4 year payment.
I only new about the extra £100 as I kep my previous car just under 5yrs and was gobsmacked when I recieved the additional £100 GCB. If I had kept the car a couple months extra I would have recievd £250 GCP!!
