nice price, good shopping cart experience. Minimal product info on part I ordered and no picture. But if the right part arrives, I'm happy!

Excellent price.....Excellent service......Super Excellent Packaging for Shipping !!! I however did not expect a Behr brand radiator to be China made.....I was really expecting a Brazilian made product like OEM...... And to be honest, although the part is new, the overall appearance looks to be 20 years old like it has been sitting on a shelf somewhere for that long.....

good price

YEP

Shipped quickly! Hood Lift supports are exact OEM brand!

You had the product I’ve been looking for. Shipping is very high for the small item but is needed
