B4 OE Replacement

I am a little unsure that this is for the 6 ft bed.

We ordered a Thule 9003 Raceway 2-bike rack for my 2011 Honda Civic and it arrived in 2 days. We were very surprised at the fast service. I also had my thoughts that it wouldn't be the exact name brand product I was looking for and a off brand but the same type and I have to say it was exactly the product I wanted. The price was great too. I researched several dealers and Autoplicity was the lowest price at $100 less than others and that included the shipping. I would definitely order from Autoplicity again.

Excellent service, incredibly fast shipping and delivery. Would DEFINITELY do business with again.

Recently placed an order for some head studs for my car. They were much less expensive at autoplicity than elsewhere. I was surprised I hadn't heard anything back after a couple days, but was reassured that orders are processed within 24 business hours (3 days), not 24 hours (which I misread in my confirmation email). Just received a shipping confirmation with a tracking number today.

They made a mistake with the shipping address, but, they took care of it very politely and professionally. Very nice. Thanks.
