"Yesterday afternoon I ordered 2 bumper mounts for a P38 Range Rover. This morning at 10 o'clock they were delivered to my home. I feel I must congratulate you and your company for service beyond the call of duty. This means my car will be off the road for less than 24 hours. To say I am impressed is an understatement and you have got a customer who will not only use your services again but will recommend you to all my Land Rover friends as well. Thank you once again for outstanding service." Customer Comment
