The experience was mostly positive. The sales staff were not always responsive to my emails though, and someone from the nuvista team slipped some shady changes through on a change order they said was for something else. Mostly good experience, but a few interactions were less than ideal in terms of professionalism and responsiveness.
The sales experience with NuVista was excellent - Sana provided us with incredibly good service. However, there have just been too many other hiccups (specifically since taking possession) along the way for me to remain trusting in Nuvista.
