Killion Auto Sales updated their business hours.


Over the past several months the chip shortage has wreaked havoc on the car industry. We have seen historic low availability of new vehicles at dealerships, and consequently that has led to far fewer available vehicles for used dealers to stock our lots. As we navigate the challenges of operating a car dealership with a severe lack of cars, Mike and I have made the decision to close our lot on Saturdays for the foreseeable future.

This decision does not eliminate a day where we are normally able to purchase new inventory, but it does allow us to reduce costs and spend more time with our families until the situation improves. We will continue to remain open during the week for our normal business hours, and as soon as we are able to build up inventory again we will resume our Saturday schedule.

In the meantime, thank y'all so much for your continued business. Please reach out if you have any questions about how our change in hours might affect you.

Nathan Killion


We will be closed Saturday May 29 - Monday May 31 for Memorial Day. Normal hours will resume on Tuesday June 1.

Compounding issues for car dealerships leave lots at a bare minimum 04/27/2021

Compounding issues for car dealerships leave lots at a bare minimum

Compounding issues for car dealerships leave lots at a bare minimum Dealerships have been facing supply chain issues for some time now, leaving their inventories low. A string of Central Texas storms has compounded on top of that for the car industry.


Folks, I promise we have inventory right now, and we're not going out of business. Right now stocks are low due to inventory shortages throughout the nation, and most of our inventory is selling as fast as we can get it ready. That means our website will often lag far behind what is currently available.

If you want to know our most up-to-date inventory please give us a call at 512-255-4555.


Like many of you, we have been stuck at home without power for the first part of this week. Now that power has been restored, we’re keeping an eye on driving conditions to determine when it will be safe to reopen.

We will try to reopen by tomorrow afternoon, but if the roads are still bad we will wait until Friday. I will post here as soon as we’re confident of when we’ll be back at the lot.


With the winter storms making driving conditions poor we do not plan on opening before 12 tomorrow. Depending on weather and road conditions we will remain closed until it is safe to return for both ourselves and our customers.

Stay safe and warm out there.


We will be closed from 12 pm today 12/24 through 12/27 for Christmas. Normal hours will resume on 12/28.

We will also be closed 1/1 for New Year's Day, and will be closed like normal on Saturday 1/2 for the first Saturday of the month.

Merry Christmas from our family to yours!


We will be closed tomorrow Saturday September 12th. We apologize for any convenience. Normal hours will resume Monday September 14th.


Phone lines are restored.


Our phone lines are down this morning, so if you need to contact us please do so through email or Facebook. I will post once our phones are restored.



Starting Monday May 4th we will be returning to our normal business hours. As a reminder, normal hours are:

Monday through Friday 9:00 to 6:00
Saturday 9:00 to 3:00
Sunday Closed

Starting Saturday May 2nd we will be closed the first Saturday of every month.


Starting Monday April 27th we will begin to expand our hours back towards normal.

New Hours will be:
Monday through Friday: 10 am to 4 pm
Saturday: Closed
Sunday: Closed



Now that Williamson and Travis counties have issued shelter in place orders to eliminate all unnecessary public interaction in the hope to "flatten the curve" of COVID-19 spread, we are again readjusting our schedule.

Auto Dealerships are classified as an Essential Business by the orders, meaning we are able to be open during this time if we so choose. However, in the spirit of the orders, and in hopes of keeping as many home and safe as possible, we are going to significantly reduce our hours to provide only necessary service for those who need transportation.

Our hours going forward will be:

Monday thru Friday : 12:00 to 4:00
Saturday : Closed
Sunday : Closed

These hours are in effect through the time decreed by the county orders (April 13), or until circumstances cause us to change them once again.

If you have questions during off hours please visit our website to find contact information or message us here.


Mike and Nathan Killion 03/20/2020


Two announcements in the midst of the shut downs and self-isolation most of us have been dealing with for this past week and will continue to live under for the next several at least.

One, if you need to make your monthly car payment and you usually use a credit or debit card, please consider using our online payment portal to limit your exposure and ours to any risk of infection. You can find the payment portal here :

Second, starting today 3/20/2020 we are implementing new hours until this crisis is over, or we are instructed by the government or our own good sense to do otherwise. These hours may shorten or return to normal depending on developments in the situation.

Temporary Hours
Monday thru Friday - 10:00 am - 5:00 pm
Saturday - 10:00 am - 12:00 pm
Sunday - Closed

We appreciate your cooperation and understanding during this historic time, and hope and pray that all of you are safe and well over these coming weeks and months.

Thanks as always for your business, and we'll let you know if anything else changes.

Most days at quitting time we're too focused on shutting the office down so we can get home to our families, but every so often you catch a sight of something that will stop you in your tracks. Mike snapped this picture of the beautiful sunset outside our office last night, and it's a reminder that sometimes there's something worth slowing down for.
