When I bought my CT, the Finance guy told me that the only credit card they accept is the Lexus card and you can only put a maximum of $3000 on it at purchase.

I don't know if this is a corporate mandate or a dealer-by-dealer decision. Anyhow, both my wife and I opened up Lexus cards and put $3000 each on them.

$3000 X 2 = $6000 = $300 worth of Lexus points.

That's because CC companies charge the seller a % of the transaction.

Visa and MC usually around 3% - Amex 5-6%

This would be a cost to dealer (3% on 20k is $600)
