Reliable dressage horse

Wanted reliable dressage horse, correct movement, height 162 - 174, uncomplicated character, minor remarks or stable defect should not be a problem, age max. 15 years. Preference is given to a horse with experience, but the horse must at least be well ridden. I am not looking for a sensitive or very sensitive horse. May be mare or gelding, with a slight preference for mare in connection with breeding. We also only have mares at the moment, so if it is a gelding, he must be able to go out with the ladies. I am looking in the normal price range, so horses with an asking price above 15,000 euros are unfortunately above budget.
