False advertisement, leading to bad CarGuru rating

I selected a vehicle and messaged the dealer via the CarGurus page, via the
prepared messaging link along with my information. There were a few text
exchanges with dealer representatives, and I went to see the car the next
day. To make a long story short, I wanted to pay cash for the car, and after
speaking to the manager the sales rep advised me that the advertised price
was only for financing and not a paid in full sale. Needless to say, I left the
dealer. There was no disclaimer anywhere on the CarGuru page or dealer
advertisement. The closest thing to it was a message I was sent, letting me
know that the vehicle was eligible for financing. A complete and total waste of
my time, and blatant false advertisement. Does CarGuru allow these
predatory practices to occur? The "great deal" rating definitely did not apply
for this vehicle, as CarGuru had rated it.
