Legally speaking, the dealer owes him nothing. From a moral standpoint, the only item in question is what the salesman said about the CEL being on. If the salesman was BSing the customer by saying the CEL was on from a sensor (without actually knowing if this is true, or if the CEL is on for a larger problem, say a tranny issue) then this is a morally flawed salesman. This however, does not help our friend jhigbee, as he bought it as is.

I agree with your post (#33) as that is also a fine option. All good advice.
