GREAT !

Very fast delivery

Easy ordering experience. I used PayPal and made it secure and seamless. The packaging was superb. The widget used to define the fitment was perfect - I have a '93 British SUV and its not always easy finding exact parts and the fact that it was a Bosch made it better.

Had to leave site and go back. It wouldn't go to pay pal!

If it does ship as fast as you indicated, I will be back for all future RV parts purchases.
