Not exactly.
These counties require an emissions test to register a vehicle:
- Boulder
- Broomfield
- Denver
- Douglas
- Jefferson
- Portions of Adams
- Portions of Arapahoe
- Portion of Larimer
- Portions of Weld
BUT here's the REALLY bad news. Thanks to Hickenlooper Colorado this year started following the California Emissions laws. So that means ALL vehicles 1976 and up need to pass emissions at least every 5 years (for 32 year old and older classics) and every 2 for newer cars. Also the emissions testing is now more stringent. Not exactly sure what's changed on the older cars but for OBD2 they look at more parameters in the ECU, that means NO TUNES. Then there's the "CARB Approved" parts issue, some meth head cut the Cat out of your truck? Now it's going to cost you 4x as much for CARB approved CAT because it's illegal to ship/sell "Federal Cats" to Colorado.
The mouth breathers at the Air Care facility don't care if your swap burns cleaner than what it replaced, all the items on their list must be intact, that means AIR Injection system, EGR, Cat & Evap are all in place. They also have a gas cap integrity test, this is the #1 failure. Lube up your O-Ring with Sil-Glide or White Lithium grease and you'll pass. I had a BRAND New cap fail this B.S. test.
I along with several other people believe this how Air Care had stayed in business, this failure is easy to fix, but shows that their testing is valid because they identified X-failures per year and X came back for a retest and passed therefore cutting down on pollution. If 99% of the cars coming in passed on the first shot, they'd shut down the testing as it's a waste of money (this happened in many other states).
I understand Texas is a hot and generally a miserable place to be outside 1/2 the year and Colorado is very appealing for the outdoor enthusiast, but the Front Range has turned into a cesspool of drug addicts, bums and Extreme Liberals from California. In Denver it's really gone down hill in terms of crime and vagrants all over the place.

If you DO come to Colorado, register your Elco up in South Dakota. Easy.
I saw you visited Estes Park, that's close to where I live. Keep in mind with the Mountains as you go further up the longer your winters will be. Places like Black Hawk or Rollinsville are in relative close proximity to the metro area and tick off all your boxes but you'll be shoveling snow from Oct til May. Further up will get your farther from Health Care, the Airport and make winters that much tougher. Estes is close to being the sweet spot which is why we have so many retirees here and yes the Summer is crowded with Tourists but that drops off cliff outside the Memorial Day-Labor Day season. Another bonus to Estes is it is outside of Air Care. It's a real give and take with the Mountains; Cheap and it's going to be FAR from any services, close to the action it's going to be EXPENSIVE.
My personal Favorite place that's in the Mountains is Buena Vista, it's not the harshest winters, tolerable summers, not extremely expensive and tourism is moderate. It does have a HUGE prison which is probably why it's not in HIGH demand
