WT Blue Rey aka Rey is a 6-7 year old warm springs mustang registered with NAMAR I would say she definitely could be a confident beginner horse with a trainer as she can be stubborn.

What has Rey done?
Crossed water
Rode passed cars, garbage trucks, and lawnmowers
Been lightly started in jumping
Shown English equitation and western pleasure
Dragged poles and pallets
Swung rope off her
Been rode by beginners
Trotted pole and barrel pattern
neck reins

Pros of Rey
Easy keeper
sound
W/TC broke
Not Spooky
UTD on shots
No buck, bolt, rear or kick
Rode in snaffle or bitless
Cons of Rey
Needs some consistency no more then two-three days off
Can get hot? Took her trail riding and my friend went off cantering Rey did get excited and wanted to follow but all she did was walk faster.
she will test you and see what she can get away with but all that is her walking to the wall and standing still

Overall Rey is very manageable and needs a job she has a great mind.
I have videos of her being jumped, rope swung on, dragging poles and pallet, riding doubles, beginner rider, trails.
