Depends whether or not the value of the sale is that one-off purchase or if a percentage of previous customers will buy again. In the case of the latter, you need to factor in the long term value of a customer before deciding which is best. Many businesses have loss-leading products for this very reason.
On the subject of price - it'll always be a deciding factor within certain markets. Mid-end cars will usually sell en-masse and based on price. High-end cars won't though (some will, but those customers tend to be mid-end flirting with high-end). Where does your product sit in your market?
