Rented a compact car with these guys for a week on Maui. I have used them before (my old review can also be seen on this site). They just get a discounted rate for Alamo cars which is fine by me. Booked online, everything was smooth.
Only gave 4 stars this time because this time I saved $50, and last time it looks like I saved $100. Also, the email address that Alamo got was not correct so I was not able to get an e-receipt (though cant say for sure if that's their fault).
