Very nice vehicles at good rates
While the Sixt vehicles were parked at the very end of the garage (Portland airport), I did get to walk past all the $50k super bland rentals at all the other vendors before stepping into my $130k vehicle from Sixt. For the long weekend, this fancy car was only about $100 more than the typical rental from my old rental company (and that's with the hefty corporate discount from the old rental company). Sixt also gave me a digital check-in that let me skip the counter in the rental car terminal. Most of the companies had crazy long lines. Sixt also had a line, but I didn't have to stand in it! Went straight to the vehicles, where a friendly agent gave me keys in fairly short order. Return was even easier, with good signage and another friendly agent right there to check the vehicle back in.
