Need advice o

My 2008 Prius with 160,000 miles was recently totaled when it hit a deer, and the age/miles was supposedly not worth the cost of repairs. Florida has weird laws regarding buy-backs, so I can't really my get it repaired on my own. I loved that car.

So, in the market for another Prius. Looking at Gen 3, here is what I've narrowed it down to:
2013 Four 90,500 miles with moonroof for $13,000 out-the-door & 30-day warranty
2014 Two 52,300 miles for $15,900 (not sure if their 12 month certified warranty is extra)
2014 Four 63,800 miles for $14,000 (warranty is extra)

Questions:
How reliable is the moonroof (not solar - just plain)? While I would love that feature, I like little to the little to no maintenance besides check-ups better.
Would the extra 30,000 miles of the one-year older model be worth the $1,000 savings?
How risky is buying a certified pre-owned vehicle without an extended bumper to bumper warranty be?

I'm on my own here in a new area, so I thought I'd consult the folks who always helped with questions I've had in the past - YOU.

 

I'm in Northeastern Florida near the Georgia border. I was averaging almost 19,000 per year, but since moving, I'm guessing it will go down to 13,000-15,000. I always had service done at a Toyota dealer, but given the closest is now 30-50 minutes away (depending on traffic) I may switch to something more local. I hadn't even thought of a plug in - are they as reliable?
I'm guessing with the constant sun (& relatively close to the ocean), the stripping degradation might be an issue here as well.

I appreciate your help.

Edit: The Prime is way out of my price range.

 

You can tell how satisfied I was with my little 2008, I hadn't even heard of the Gen 1 plug in.
I'll check into that.
