Thank you for all the brill advice. It went very well thanks! The place was very smart and well kept. It was actually a dealer which I knew in advance but I am confident they have a good reputation and I have searched for bad reviews etc and can't seem to find any. Also lots of people have posted pictures with their horses they had bought from them a couple years back saying how pleased they are etc, so I was confident that they wouldn't try and sell me something that wasn't right for me.
I actually tried two horses the first time I visited. One was a bit more lively and slightly younger which I didn't mind but I deiced that the slightly older horse who was more laid back (but still had some power!) was a safer option and I felt looking back at the videos of me riding her I looked 'more the part' on her. So anyway I went back to try the first one I rode again which went super and although she was the first horse I tried she is exactly what I was looking for. Safe and sensible for a first horse, I was able to try every thing I wanted to do with her and I believe she is going to help me move forward with my riding! They had lots of videos of her and I got to see her passport. Nothing dodgy at all. We made the decision that she was really ideal for me and so subject to vetting hopefully I will be an owner very soon!!
About to post a new thread asking for advice about vetting too so look out for it! Many thanks everyone!!
