Good pony to train yourself - without bad experiences

Good pony to train yourself - without bad experiences - The pinto gelding pictured here is still looking for a suitable home.
He was originally bought as a driving pony as a weanling and has been with one owner throughout and has never been ill there. He was broken in three years ago, but was then no longer ridden due to the owner's illness. He stands at the house, is in your hands every day, but is not trained.
He runs barehoof and has strong hoof growth. He knows traveling, rides in a trailer, guided walks, camping, swimming at the lake.
He has always been absolutely well-behaved here, safe on the road and off-road.
