My Story

We live in a world contemplating the extinction of the internal combustion engine, yet so many of us have an inextricable passion for motor cars of all ages, and the story behind that passion is always very personal. This is mine.

When I was twelve, a pair of Horch 853 Cabriolets emerged from a long slumber in my hometown of Manchester, CT. Having been recently acquired by the proprietor of a newly-established restoration facility, my dad took me to see them at Manchester Motor Car Co. I was entranced by their historicity, and that visit sparked a passion that would become my vocation. A few years later I inquired about summer work with the owner, Butch Gordon.

One of the best parts of Pebble Beach week – visiting with friends at the start of the Tour d’Elegance.
Speaking on the running board of the Nanaline Duke Duesenberg at the Audrain Museum gala in Newport.
Visiting with legendary Connecticut native John Fitch at the 2008 Greenwich Concours d’Elegance.
I was on the build crew (parts chaser!) of a Bonneville Lakester early on in my career at Manchester Motor Car.
One of the Horchs was sold when I was about 17; I'm glad to have gotten a farewell snapshot.
Taking a break with friends on the runningboard of a Packard Custom Dietrich at the 2017 Pebble Beach Concours d’Elegance.
He drives a Duesenberg – on a rainy segment of the 2016 Duesenberg tour.
At speed on the third day at Bondurant driving school in 2013.
Driving one of the masterpieces of the Classic Era, the 540K Spezialroadster.

Sweeping and car dusting gave way to work in the parts department with inventory dating to the 1920s. As I learned how component parts made engines run, my summer job turned into weekday afternoons and weekends, and many summers thereafter. I am forever grateful to Butch for that opportunity.

This continued during my time at University of Connecticut, where in addition to academic studies, I began writing auction descriptions. Through the auction world I met Rick Carey, who eventually hired me to help report on some of the many sales he attended. Rick introduced me to the truly great cars, educated me, and made introductions that helped secure freelance work from most of the major auction houses. Among those organizations was RM Auctions, and a year of freelance gave way to a full-time role that rapidly evolved with many exciting opportunities; it was an amazing journey for which I feel most fortunate. Motivated to work closely with the coachbuilt automobiles I always gravitated to, I founded Sierakowski Classic Car Advisors in January 2017. I look forward to sharing my passion and client-oriented focus next time we visit.
