Help with review!

I found several cars I liked on Carguru.  I
printed out from Carguru all the information
for these cars.  On the same day I printed
the paperwork from Carguru and the
Dealerships website they changed the
price basically while I was test driving it!  
As I'm driving the salesman riding with me
said where did you find us.  I said online.  
He said oh which price did you see.  I said
huh.  He's like oh we had to go up on price
today.  It's not 15.4 anymore it is 18.9.  I'm
like ummm no I just printed out a paper
before getting in my car to drive here the
price and you should honor it.  They went
UP 3.5k!  As I'm driving it they told me the
car had strut issues.  I also saw before
driving a cosmetic piece was missing from
the back passenger side (shows in pics
they have posted it's there).  My husband
called to basically say wtf!  The manager
gave him some crap story about how I
insisted and my husband knew he was not
telling the truth because he was on the
phone with me as I was reviewing the car
to him on the phone as walked around it
and looked inside.  After I looked at the car
and decided it looked good I said ok let's
test drive.  The sales guy already had the
keys in his hand and that's when I told my
husband I'd call him back.  So when my
hubby told them that was crap then it
turned into he's a new sales guy and got
the keys before asking if it was ok to drive
it!  Making up all kinds of crap to get out of
the fact they let me and my special needs
baby test drive a car they "deemed
unsuitable to drive".  I fully believe so they
wouldn't have to honor what we had in
print the manager said the car had now
been deem unsuitable to drive (this is a
Buick dealership and my husband was told
this within 15 min of me leaving the
dealership it was now unsuitable to drive)
and they were taking it off the market until
it could be repaired or go to auction.  They
still have it listed here & other places at the
higer price!  They even now have
sponsored a post for it!  I'm trying to leave
a review so a customer doesn't get tricked
by this vehicle or the shady people who
work there.  Since I didn't make contact
through Carguru it won't let me leave a
review.  How can I leave one so I save
someone else from this shady dealership!
