Premium Package? I got quotes form car dealers.

2008 Accord LX-P AT
Dealer price $21,121; their invoice price $20921 + 200; plus tax, doc, plate fee.
(Edmunds invoice price $20,085 )

2008 Lexus ES350 with Premium Package
Dealer price $34,288 plus tax, doc, palte fee
(Yahoo auto invoice price $32,002).

It looks like Honda dealer's inovice price is very close to edmuns' price. Should I negotiate the price down more? If I can not negotiate down the price, any chance I could talk to them give me free tint glass?

The Lexus ES350 is $2000 over the yahoo atuo website. Is that reasonable price?

I really like Lexus. If I could get the price very close to the yahoo auto site, I might consider go for Lexus. But if there no hope for $2000 less, I will go for Accord.

Really need help soon!

Thanks!
