COMMUNITY TESTIMONIALS
@vader_F32
Have been using Mashimarho for all my BMW needs since i bought this car 5 years ago . The team at mashimarho always does a great job in bringing the best price to the customer and doesnt stop there , they also have one of the best service ive seen . Shipping is always on time and they will always help you figure something out on a time crunch . The quality on their house made carbon parts is phenomenal. As long as i have my car and i am doing mods to it , Mashimarho will always be my first stop for parts ! - Neel

As a repeat customer of now over 4 years, I’ve always found confidence in returning to Mashimarho time and time again because of the communication, consistency, and care that goes into the work they do. From custom carbon fiber trim pieces and embroidery to off the shelf parts from names synonymous with automotive performance, Sean and his team continuously exceed my expectations in delivering top notch customer service at fair and competitive pricing. Through my car’s many stages and revisions, they’ve not only catered to my vision, but have confidently offered suggestions on how to further improve the quality, performance, and styling to make my 1M a unique and impressive masterpiece. Thank you!

Mashimarho is my go to place for anything I want to do for my cars. They have helped me build my e92 m3 to perfection and now we are on to the g80 m3. They have helped me with all my needs to make my builds how I really dreamed they would be.

It is no surprise to me that Sean and his brand has become a go to business for customers from all across the world. Mashimarho has been instrumental with advice and parts for my F82 M4 Comp build since the beginning and I'm excited about the continuous evolution with their support this upcoming year. Sean not only has a great team around him...he also responds to untimely private messages any time I have a question or want to run things by him. The answer is always "can do" whether I need quick turnaround on parts or help with special installations like my custom instrument cluster plates. It doesn't matter whether you're in for just a simple item or whether you're taking on a big project.....they always treat you with equal amount of importance which is rare in today's day and age. Mashimarho is the first place I mention when others around me are looking for parts to their builds. Thanks for all the support so far! Looking forward to continuing to push the envelope!

I just wanted to give a shout out to Sean Mashimarho. Ive been looking for a set of wheels for over a month . I almost bought some when i decided to message sean . He answered every single question and concern I had about the wheels I wanted . He answered every question without hesitation ( i had a million ) . It also made it much easier because I trusted his expertise . He helped with the perfect set of wheels for my car and I couldn't be happier . I can't wait to continue getting more parts for my build from him. Thank you Sean

I’ve been a regular customer at Mashimarho since early 2018. They’ve been a part of each and every build since then and always has the best prices and customer support around. With the best deals and build quality, this platform is a one stop shop from exterior modifications, performance modifications, three piece wheels, you name it! It makes it easy to have everything handled under one roof with quick turn around time. Also with the Mashimarho team being well versed with a variety of platforms, they will always have great recommendations to compliment your build.
