The currently have another model on sale at a decent price.
The difference appears to be the motor/pump and that it has a max height of 39" as opposed to 56" so if that isn't a big deal, with the 20% coupon, you are under $800 + shipping. The min height is actually better though imo, approx 4" instead of 7"...no worry of having to use planks with the Boxster for clearance.
Strange that off sale it is actually a lot more than the other one.
