Mike did a great job working on my 2016 BMW X5 Xdrive35i. When I was describing what the issue was and provided my mileage (approx 80k miles), he knew right away what the problem was. Sure enough it was the valve cover gasket that was leaking. I opted for the BMW OEM valve cover assembly kit. Price was very reasonable. He installed it within a couple of hours. Work was done 12/08/25 and until now 01/16/26, and the car has been running smooth, with no leaks. Mike is very knowledgeable in BMW vehicles and it shows! You’ll see when you meet him. He’s my go to BMW mechanic! Thank you Mike for making me feel welcome and treating me like family.

I was referred to Mike through a friend who brought his cars here. I usually take my cars to the bigger names you see on social media but I had a few bad experiences, nothing major though. So when I heard about Mike's shop from my friend, I took a chance especially it being a little further drive for me. Mike is a stand up guy and knows his stuff. During the install, there was some issues with the part that I had purchased online. Mike made it his mission to figure it out. Long story short, Mike made it work. He definitely went above and beyond to make me a happy customer. During the install he even went step by step on what he was doing to keep me in the loop. I felt like we were just kicking it as friends and working on my car. It didn't feel like I was just a paying customer. For the wo

Took both of my X5's to mike. He's taken good care of them and fixed what I needed done. Also spotted another x5 like mine at his shop.

After growing tired of the annoying reliability of my ND2 Miata, I decided to replace it with a dakar yellow M roadie from Jersey. It did not disappoint and unreservedly satisfied my masochistic cravings with non-CARB compliant Supersprint headers and a dangly rear shock that I am sure had taken inspiration from drift tokens. Distraught, I scoured the net for local shops and was fortunate to find Mike who as luck would have it, happens to have stock headers on hand. He knew that I was under pressure to get the car registered asap and was able to help sort out the issues earlier than promised. To my appreciation, he even did complementary repairs on a couple of small items. Thanks to MotorsportMike, I was able to get my car roadworthy and registered in a timely manner. Mike is friend
