Does my car have OBD-II port?

All cars built since January 1, 1996 have OBD-II systems. Manufacturers started incorporating OBD-II in various models as early as 1994. Some early OBD-II cars were not 100% compliant. OBD-II provides a universal inspection and diagnosis method to be sure the car is performing to OEM standards.

Super easy to order and make a selection, fast shipping however the product was purchased as a gift for someone else so I can't elaborate as far as how well is going to perform.

Hi Geza, thank you for purchasing from us! So glad to hear that you love the ThinkOBD 100! If you have any questions, don't hesitate to reach out and ask.

The scanner arrived in a very timely fashion and was well packaged to avoid the damage that occurs sometimes during shipping. I put it to good use right away, which I may add was very easy!! I am not experienced in using OBD Scanners, but this one made me feel as though I was. The box is low profile and the unit goes back into it with ease as well. It stores in the glove box very easily and mine will come in handy again and again. I definitely recommend getting one for yourself, and it would also make an excellent xmas gift .

Hi Greg, so glad you hear you love our lineup of OBD scanners. Great to hear!


Work perfectly well. Arrived on time.

Hi Pierre, thanks for leaving a review!
