I bought a used Dodge Charger from your dealership...

I bought a used Dodge Charger from your dealership in Austin, TX. I noticed an issue with the transmission shortly after buying it and when I took it to the local Dodge dealership (Not Asbury Dealer) they told me the transmission was 3 quarts low and needed to be replaced. I've been trying to work with David McDavid to get the issue fixed but they have offered no help. I know I bought it as is, but the lack of customer service will keep me away and any one else I can warn about this dealership. Very disappointed!
