Save your time and do not visit this dealership!

Reviewed by Alba in ChicagoMay 29, 2021

Drove an hour and half to put a deposit on a vehicle that they then tell me was sold a month ago! How do you run a business where your employees don’t know when a car got sold, especially a month ago! Absolutely ridiculous

Misleading Experience

Reviewed by rungolfski65 in PalatineMay 16, 2021

Car availability is not as advertised; we were asked to visit the dealership and take a test drive, then were told that the car was "designated as a service loaner and not for sale". This was after 1 week of communicating by email, text and voice regarding the subject vehicle and my trade. At this time, the vehicle is still showing as available on The experience seemed somewhat deceitful.

Great place to buy a car.

Reviewed by Debbie P in Belvidere, ILNovember 13, 2016

Me and my husband have bought cars at four different dealerships, for me Gary Lang Auto is by far the best. The buying process is easy and faster then others. Some dealerships it takes all day. 
 The service department gets you in and out A.S.A.P.
