Len’s is one of the best in the business. I have never met a more friendly auto place. They do fantastic Auto work which you will see from the reviews but I also find having somebody nice to talk to when you’re dealing with a painful experience. That is a huge asset that others should try to replicate.

I’ve been using Len’s for nearly a decade now, and I couldn’t recommend them more. Great customer service, very knowledgeable staff, reasonable pricing. They won’t try to upsell you or pull a fast one on you, just an honest, local mechanic that does great work.

A Short Move, A Big Upgrade
In 2023, we packed up our tools and moved just about a mile up the road from our original Cottleville location—but the change was anything but small.
We made the move to better serve our customers with a larger, more modern facility while staying right in the heart of the community we love. Same friendly faces, same trusted service—just with more space to get the job done right.
If you’ve been with us since the old shop, thank you for growing with us. If you’re new to Len’s, welcome! Either way, we’re glad you’re here—and we’re ready to keep your vehicle running strong.

Whether it’s routine maintenance or a complex repair, our ASE-certified technicians have the experience and the tools to get the job done right the first time.
