Steven H's, 2017 Wrangler JK RubiconCustomer Service Quality Assurance I got into Jeeps at an early age, as a child around 3-4 year of age my parts got me a power wheel Jeep and the rest was history. Growing up I always wanted a Jeep, from the day I started driving I spent my days behind the wheel of a Jeep branded vehicle, which has not changed.
