I would definitely get that over a 3. Once the Y comes out the 3 will see a massive depreciation hit and a hatchback with twice the cargo room will always have a market with both families and Uber/Lyft/taxi drivers, especially when you factor in free supercharging and 8 year unlimited mileage powertrain and battery warranty, while the 3 "pays" for charging and has a limited powertrain/battery warranty that stops at 100K for the Standard and Mid-range and 120K for the Long range.
I currently drive a used 2014 P85+, the car has been bullet proof, I got it off eBay and I am pushing 80K + miles with the only issue being a $3 door handle microswitch (which I replaced) and a $35 windshield washer motor (which I replaced), so I'm out ~$40 since the warranty expired.
My wife has the 90D 2016.5, (new nose cone and AP1) and nothing has been an issue on her car. Also I am a prior owner of a 2013 P85, which we sold after 50K miles, the only issue it had was a door handle LED that burned out, was replaced under warranty.
Other stuff, get additional
CR2032 batteries for the key fobs, and replace the tires as needed. Also if you have a sunroof, you need to clean and lubricate the tracks occasionally.
Things in the Model 3 that caused me pause to buy: 1. inferior warranty 2. no hatchback 3. lower quality steel body verses aluminum. 4. less cargo space 5. Model Y coming with proper hatch. 6. Truck coming which will replace my Model S and my Toyota FJ, 7. No sunroof 8, no air suspension 9. I've added too many aftermarket things to go backwards (stereo upgrades, security cameras, hitches, lighting, USB power outlets, etc... 10. It's a gorgeous car, and I didn't want to pay $70K for a new Model 3 that didn't tick all the boxes above for me.
Get the S and if you get a P model, you will get to see all the 3's you want, they will just be in your rear view mirror. Also if you don't live in an area with crime (like SF) then you don't need sentry mode (your in GA - 9mm works way better - no self respecting thief is going get scared off by a flashing light and a alarm) and in my house no damn dog is riding in my S, so you don't need dog mode either. I have a truck for my furry 120 lb wet muddy dog that smells like - a dog and he won't fit in a Mode 3 either.
Don't let the scratches scare you, everyone will eventually get them and any good paint shop can make those go away.
Good luck.
