It would be 5 stars if shipping date was readily viewable

Mostly everything went well, the only thing I can say I did not receive by email an order confirmation.

Thank you.

Absolutely the best bargain you'll find! Don't pay retail mark up at the parts store, buy at Autoplicity and know you're saving money.<br>.

great service, even better price! Would recommend Autoplicity to anyone.
