L&S Mobile Auto Repair

WARNING: DO NOT WORK WITH LEONARD CASTON. HE WILL TAKE YOUR CAR PARTS, KEYS, AND CASH AND GHOST YOU. THIS IS A SCAM. My initial experience with Leonard was great. He helped replace my alternator and battery over the span of a few days, and he was supposed to return to replace my spark plugs and ignition coils. He then stopped responding to me for approximately two days. During that time, I purchased new spark plugs myself and figured out how to replace them on my own. Leonard eventually contacted me and explained that his wife was in the hospital. I completely understood that a family emergency needed to take priority. A few hours later, he came to look at the vehicle again because it still would not start. After inspecting it, he told me the problem was related to the timing. Leonard told me he would return the spark plugs and ignition coils he had purchased, totaling approximately $340, and instead purchase a timing kit for approximately $200. He sent me a picture showing the approximately $200 O'Reilly Auto Parts checkout for the timing parts. He told me we could either wait several days for the approximately $340 refund for the plugs and coils to hit his account, or I could send him the $200 for the timing parts and he would bring me the $340 in cash once the refund was processed. I sent him the additional $200 because I urgently needed my car repaired. This was Tuesday, July 28, and I specifically explained that I needed the vehicle running by Thursday evening, July 30, because my father is in hospice in Iowa and I needed to travel to see him. Leonard repeatedly assured me that the repair would absolutely be completed by Thursday evening. I heard nothing from him on Wednesday, July 29, and texted him that evening asking for an update. On Thursday, July 30, I contacted him numerous times. At approximately 4:30 p.m., Leonard finally messaged me and stated that he would be at my vehicle to begin working on it in approximately 45 minutes. That is the last communication I have ever received from him. He never arrived. He stopped answering my calls and texts entirely. I repeatedly attempted to contact him and gave him multiple opportunities and deadlines to return my money, the parts/refund proceeds, and my car keys. He did not respond. On August 3, 2026, I contacted law enforcement, and police have labeled this a theft by swindle matter. The investigation is ongoing. I have also filed a complaint with the Minnesota Attorney General's Office. As of the date of this review, I still have not heard from Leonard, and this situation has not been resolved. He disappeared after taking additional money from me, while also retaining money/property associated with the parts and my car keys. I am also extremely uncomfortable knowing that someone who has stopped responding to me still has keys to my vehicle and knows where I live. Based on my experience, I strongly recommend that anyone considering using Leonard Caston for vehicle repairs exercise extreme caution. If you want to protect your money, keep possession of your keys, and actually get your vehicle repaired, I would not use him. This entire experience has been a nightmare. I feel scammed and defrauded and hope nobody has to go through this. Texts are attached.

I do not recommend this business. I was told he would come at one time and was continously delayed for several days. I paid in time and $ for him to ruin my engine completely. I went to an auto shop and was shown the damage done. This "business" hasn't returned my texts (you can't reach them any other way) after saying he would give me a partial refund, and nope, nothing not even a return text. Pay more and protect your vehicle because he took a good engine and ruined it completely it was in better shape before he got to it.

Do not trust this guy with your car. I gave him three different chances to fix my vehicle, and every repair failed even though I still paid him. He has now kept my car keys for over a week, along with money I gave him to buy a part that was never purchased. I have been calling and trying to reach him, but all I get is excuses or no communication. He has until 8 PM today to communicate with us and return our keys and money before this matter is taken to a legal level. Very unprofessional and one of the worst experiences I have ever had with a mechanic.

I needed my lower control Arm and ball joint replaced. Contacted them, they answered quickly and professionally scheduling my appointment was fast and easy within a hour came and fixed my car. I will definitely be calling back for more …

EDIT - I had Leonard out to fix my RV and off first sight everything seemed simple. Initially Leanord did a great job taking care of the work and he definately executed it well. (Spark plugs & coils). He is a great guy and treated me well. The problem is that he did not actually identify the issue even though I told him my suspicion is that the spark plug stripped out. I was told that the threads look fine and we proceeded despite the fact that the spark plug blew the coil off. I spent nearly $1000 fixing coils and spark plugs even though this issue was in the threading. This is identified as a #1 issue on my engine. I got 45 minutes down the road and the same spark plug blew out immobilizing me on a cross country trip. He messaged me back that night (it was late) and told me he would be to my location in the morning around noon after a schedule battery installation for another client. The problem is that he did not communicate with me past that and left me out to dry parked at a bus park and ride. I tried to contact multiple time (two phone calls and three texts) and never heard anything back. Moral of the story is that I was stranded for 30 hours after being lead on for 20 hours and finally hired a mechanic that came and fixed my issue for another $1000. The second mechanic also identified that Leonard had over tightened all of the spark plugs and did not properly secure the coils. Many mounting plates were broken and one of the screws was completely stripped. Another problem is that I had to go buy my own parts when he attempted to fix it. I got in the car with his wife and dad (who were great people) and they drove me to the auto parts store to purchase the parts. He used his discount which was appreciated, but it was unorthodox business practice. This is coming from someone who owns a service type business. In the end, I WOULD RECCOMEND LEONARD, but find another person for complex work and understand that you are dealing with someone who won't contribute as a long term service partner.
