Joe is the man and this website is absolutely a must have on any G8 owners bookmarked pages, this shop is crammed full of G8 goodies and I absolutely love spending my money here! Joe has helped me time and time and time again, will be buying more parts from here for years to come, happily!

James Murphy / Facebook
Joe was incredibly helpful and knowledgeable. Picked his brain on a number of different things. Ordered lights that were out of stock, he called right away to let me know and to verify all other order details. 5/5 would recommend anyone with a G8 go through Joe and his website.

I’ve placed a few orders through G8Only.

Joe is by far the best at what he does. Fast shipping, great customer service, and the most complete selection of parts for a G8 there is. I can’t think of a better way to spend my life savings.
