@bkp_duke At the risk of hijacking this poor seller's thread, as I buyer I find it very useful to hear the opinions about the price from the very experienced and knowledgeable forum members.
Likewise, I don't want to derail this, but I do want to make my reason for posting clear.
When a used car is being sold for more than a new car would (when considering the tax rebate) I see it as only fair to warn both the seller and potential buyers of that fact.
It may not have occurred to the seller, as the rebate isn't instant. Pricing the car appropriately will help them sell their car.
The unwary buyer may feel cheated if they discover this after the fact. This could impact negatively the reputation of this forum.
If they are aware of the pricing discrepancy ahead of the purchase, no such result happens.
There are valid reasons for buying at a higher price than new.
Someone may view the car as a possible collectors item (Founders or Sig for example).
They want the car now, and can get it much quicker this way.
Etc..
I'm done, I just wanted to explain I wasn't piling on and the OP is welcome to price the car however he wants. I just wanted him to be aware he was charging more than a new car would cost.
