Pony mare available 3 years old

Pony mare available 3 years old - I offer our lovely 3-year-old pony mix mare (stallion side Welsh-C descent ) available. The stick measurement is currently about 1.3m .
Our pony knows the ground work, lunge, equikinetic, extensive walks, sled pulling, as well as the rider weight of our children . However, she has not been broken in yet, which was planned for this year.
Due to her three excellent basic gaits, a suitability for dressage is well conceivable. However, we would like to exclude a later use in jumping.
Our pony is currently stabled in an open stall, although it should be noted that she is rather light-fed.
She is in good health. All vaccinations are up to date as well as her teeth have just been done.
There are monthly costs for OP insurance etc. approx. 60, - € to carry likewise a liability insurance would be to be proven.
If necessary, a later purchase option would be possible.
