Many, many thanks to Adam Wilkes, Lee Cousins & everyone at Sixt. I was informed the Holiday Cars program has ended & Sixt should really let people know that via their main website. It was very popular. That said, Adam & Lee have been extraordinary; in fact, profoundly good with their communications and willingness to assist us. Although we could not get the prices we expected, Sixt should REALLY be proud of employees like this. Adam was VERY quick to respond to multiple emails and a wonderful willingness to assist, a level of service quite higher than we've seen anywhere (especially in comparison to other car rental agencies). Wow. What amazing people. This is how you get return customers for life.
