IAG (Integrity Auto Group) was established in 2004, initially selling high quality used performance cars. Within a year and a half, IAG sold over 200 Subaru WRX / STI’s. Our clients began requesting us to provide performance products and services for their Subaru’s, which we quickly catered to. IAG extended these services and parts nationally by 2007. Fast forward to 2019, IAG Performance is known as a leader in the automotive performance industry (specifically Subaru) and carries an impeccable reputation among our clients and peers.
