Great shipping. Product worked as it should
Super fast shipping and a exact match to my camry se. Will be using them in future.
The wheel was the perfect replacement and matched my other wheels. The shipper choice of Fed Ex ground, not so good. Your website indicated UPS ground and my request to use them with my order went unnoticed.
Couldn't have had better service and the rim was perfect!
One of the cheapest options for the same product. No hidden fees like other websites, and free fast delivery!
Quick shipping, right productand at a great price. You all have set yourselves up for success with the way you do business.
Wheel is great fast shipping
Fast delivery with good protection on parts
I loved the produc just like the pictures, i 100% recommend buying from this company, and i will be buying again in the future :)
Item as described fast and easy order thank you
Perfect fit good price fast delivery
great! turn around/delivery spot on. I'm gonna order another two wheels. Just wanted make sure it was a match. Swapped out the tire on the new rim and it balanced out zero. That's amazing.
Exactly what I ordered for the restoration of my 2004 Crown Vicky
It is what it is. Replacement takes 2 minutes and low power issues solved.
