Showroom One was founded by young entrepreneur and Bentley University graduate Grant Darst in the year 2015. Grant started detailing out of his parents' garage when he was only 16 years old, and quickly found his passion therein. Originally, Showroom One was a fully mobile detailing company; in 2015 Grant outfitted a cargo van with all of the equipment and products necessary to detail a car anywhere. After a few years, the importance of a climate controlled facility became paramount, and in January 2020 we moved into our beloved Showroom at 837 Upper Union St Unit C-5 Franklin, MA
Today, Showroom One provides a new look on the traditional detailing service, offering a wide variety of services to appeal to any car owner. We are fully licensed and insured, and our shop is completely monitored 24/7.
HIGHEST RATED DETAILING BUSINESS IN THE METROWEST!

Grant is one of the best detail businesses I have come to know. I have been to many before a friend recommend me to... grant. He pays super attention to detail and treats your vehicle as if it his very own. The rates he charges are more than fair. Uses only the best quality products on the market as well! His team is highly skilled like himself. Highly recommend bringing your vehicle to showroom one no matter what level of detail your looking to accomplish.read more

Grant showed up At my home to detailMy wife’s Range Rover. I’m not a review guy, but when people go above and beyond I... want others to appreciate the fact the pride in work still exists. Even with expel and a ceramic coating, this thing wasn’t looking pretty and I can’t say enough about how pleased I am with this detail from Showroom One. The business name is perfect because my car is now ready for the showroom! I consider myself passionate about cars and I’ve done my own “detailing” my entire life. What I do is amateur hour. Grant’s level of clean is “car show” quality! I look forward to many more details. If you are reading this review, chances are you need a detail. Don’t even hesitate and make your appointment today. You will be glad you did! Please support this talented entrepreneur.read more

I came across Grant's detailing company by chance on Facebook and thought "...remote car detailing, that would be super... convenient! But how good a job could they do?" I reached out to Grant to inquire. He was extremely responsive, professional and very accommodating! He showed up a few minutes early and got down to assessing my very dirty car. (I was on the phone when he arrived) Within a couple of minutes he came over and introduced himself and professional explained what he recommended I have done. He talked about my car as if were his own prized possession and said he would restore it to her original glory! When I say he set the bar high and over delivered it is an understatement! My 2006 vehicle looked, felt and smelt brand new! My intention was to get it cleaned up a bit and put away for the winter but Grant made it look so nice I had to drive it a few more times! If you are in need of a detail, or even if you aren't, call Grant, his rates are reasonable and his work is second to none!! Thanks Grant! I'll be calling you again soon!! -Seanread more

Several months ago Grant approached my son and I at the local DDs and gave us his card for detail work on my BMW i3. My... son (7 year old OCD) has been begging me to call him ever since to schedule. I finally did it and scheduled the supreme package as a birthday gift to myself before heading off on business for a few weeks. It was AMAZING!!!! Such a fantastic job. Came to our house and worked his magic and the car is like better than new. My son is in love and is making sure no one gets messy in the car. You have made us so happy and the car is beautiful. No longer will I be ashamed to let co-workers in my car (and parents who know me from school drop off know what I mean) ;-).
