@BlueberryT tough call. I would say if you
need a vehicle quickly (e.g. you don't currently have a working vehicle, you're sharing one with partner and really need two vehicles, etc.) then it's probably wise to try the 2020. You could always reject it outright when you go to pick it up if you notice significant issues. On the other hand, if you're not in a rush (I hate waiting for something once I've made up my mind!), then it's probably worth waiting for a new build. That's just my two cents though.
