Buying From Unstoppable Auto, LLC

Common Questions

Is Unstoppable Auto, LLC a good dealer?
Unstoppable Auto, LLC earns a C in the PPI Auto Buyer's Guide. Mixed. Many buyers were happy, but a real share were not. The grade reads 173 public reviews averaging 4.0 stars, with 23.7 percent at one or two stars. It rates past buyers' experience with the dealer, not any single car.
Can I get a car at Unstoppable Auto, LLC inspected before I buy?
Yes. PPI Auto sends an inspector to the car on the lot in Knoxville. You do not have to be there. The inspection covers 122 points, a full OBD-II scan with readiness monitors, a road test and photos of anything found, and the report comes the same day. Ask the dealer to hold the car while it is checked.
How is the grade worked out?
It needs 20 or more public reviews. The star average is pulled toward the national average by 25 average reviews so a short record cannot jump the line, and the share of one and two star reviews sets a ceiling. The full method is on our grading page.
