Koko Zarov

Luxury Sales Associate
303.469.1801 x.6524
Koko did not get his name because of his love of hot chocolate.  Turns out that it's just easier to pronounce than his real name, Kaloyan.  He joined Sill-TerHar in 2014, but he joined the USA in 2011. Since then, he has been proud to become a luxury vehicle sales associate at Sill-TerHar motors.

Molly Marston

303.469.1801 x.6503
Molly has been at Sill-TerHar in one form or another since 2007.  She has five members of their family that celebrate birthdays on a holiday, which means none of them were born on Easter, or Thanksgiving, since those are moving targets.  She's a proud grandma, and is learning to drive four-wheelers, which I took to mean driving on for wheels, but was quickly corrected. Finally, and I hesitate to say this, but she's very much into... "girly stuff".   I'll let you imagine what that means.

Jack TerHar

303.469.1801 x.6514
Jack joined his dad's dealership in 1970 and was quickly shown to be a natural in the automotive business.  His success at building a wonderful family and business stem from an innate ability to win friends and influence people.  His close relationship with the manufacturers has led to a unique perspective on the world of auto sales.  On his down time he is an avid golfer and loves to travel.  More than anything is proud of what Sill-TerHar has become, and values that his entire family can be involved in it's continued growth.

Steven Leonard

Sales Manager

Steven joined Sill-TerHar in 2008 as a luxury pre-owned salesman.  He is now our luxury sales manager.  He is an avid baseball fan and has been a Colorado Rockies season ticket holder for since their inception.  He enjoys travelling and has been all over the world.
