Wanted 15.2 - 16 HH horse good in traffic and kind nature

I am an experienced kind rider looking for a 15.2 - 16HH horse that is good with traffic and will load into a trailer. Something with a kind easy going nature, doesn't have to be good at anything else. Older horse not a problem. My old girl in the photo is now 24 and needs to have an easy life and her side kick my 31 year old Shetland. I have my own land and stables at home and am happy to keep in contact with sellers and offer a permanent loving home. Budget four figures. Yorkshire, North east area please
