Welcome, and congrats on your decision to get a Slingshot, let the fun begin!
First off, do your research, go online and build several out, become familiar with the options and what they do and do not do for you for you. compare the prices. Unlike cars where you can get any model in any color you want Slingshots are model specific to the color with a few variations. So if color is important start there. Then look for the autos. Only 2020 and 2021 offer the auto. The 2021 has some upgrades to the Auto with paddle shifters and new programming. That can also be added to the 2020.
Depending on how bad you were bitten by the bug the best way to look at options, (aftermarket) and get the scoop on what they do is to see them and talk with people who actually own them. Get on Facebook, check out any Slingshot clubs in Albuquerque, get out and go to one of their meet ups. That is where you will get a true idea of what you want and don't want, They can also tell you about the local dealers who deal and service the Slingshot. They can tell you who has the cheapest insurance coverage for your area. Slingshot owners as a group are the friendliest people you will ever meet.
Good luck.
