I know -- that's what I'm a little leery of! Anyway, I just spoke with the driver (Anthony@ Quad County Limo) and he assured me that he is licensed and this is the real deal.
I asked why his rates were so much lower and he said he is looking for more volume and hopes that providing decent airport transfer rates might lead to more referrals as well as vacationers that want tours of Hollywood, etc...kind of what you did Lollipop's Mom!
I went ahead and paid in full through PayPal using my credit card so at least I feel somewhat protected. Of course that won't be much consolation if the 8 of us are sitting on the curb @ LAX with no limo in sight.
BTW -- If anyone else gets a quote and talks to him, be sure and mention you saw the info. on this forum as I told him I would pass it along. Maybe if enough of us start using him we can ask about a discount of some kind.
