Thanks akirby, that worked!
It looks like...
Total MSRP - $48,440.00
X Plan Price - $44,179.00
So basically, I think I'm better off with the $4400 off MSRP that the dealer is offering because then I can also use the AQHA rebate.
48,440 MSRP
(4,400) "Dealer discount"
(500) AQHA
(4,000) rebate (or 0%)
(1,000) bonus cash
$38,540
Actually, with fees and stuff the X-plan is probably a wash ... like you said earlier.
Thanks again.
