This is only the 3rd 4 wheel I have ever driven so view my opinion with that in mind. Other than the fact that it's a bit short for my 17h Percheron mare, I love it. I bought it because I wanted a lot of flexibility. It was light weight enough to work on both my smaller horse/large pony and my big mare (with a bit of alteration). I have never once felt like I would flip and I take in places I probably shouldn't...tight turns, very uneven terrain, etc. There is really a lot of flexibility to the carriage and I have plans to make some additional modifications to make it more showy for dressage. I love the navigators area. With the great flat wheel covers/seats I have had 3 people on and off the back as we went on a trail ride/drive. I also navigated at the prelim level off of a PJ and did not notice anything being in the way or layed out weird. The Hideout is a small workshop on the owners property and because of the small operation there is almost a year waiting list so be prepared to wait a bit to get your carriage, but don't let that deter you from buying one. I gave a 2 on the comfort because I really prefer a much snugger seat. I find myself bashing into the sides which is uncomfortable. I think the seat might be a bit better for a behind bigger than mine. :-)
