Currently Honda is offering a $6k purchase or lease credit on any new clarity plug-in hybrid.
Purchase a Clarity or Clarity touring and get $6k Honda credit ( to dealer for purchase, can be passed to you) or passed to you for lease in lieu of $7500 federal tax credit for leases.
Normally the $6k should be for lease but applies to finances or purchases until 7/8/19.
Essentially you get $6k +$7.5k off for any purchase + any discount you negotiate.
Most dealers are taking up to $1500 off. YMMV. If you are in a state with high documentation fee please back that off the price, it's dealer profit.
Honda discount 6000
Dealer discount 1500
Tax rebate : 7500
Price : $19320 for base model
Additional state incentives : https://automobiles.honda.com/clarity-plug-in-hybrid scroll down half way through.
Currently own a Honda or recent grad or military? Take another $500 off (250 is funded by Honda and 250 by dealer, so a minimum of $250 should be taken off with no impact to dealer profit).
Want a 7yr 100k warranty? Don't buy it with your dealer. Many Honda dealers will happily sell it to you for $1300+tax (same Honda warranty).
