Be sure it is really clean... does not smell like smoke... those kind of eye wash types of things , have it parked where they can walk all around it... tell the truth about what you know about the car.... and if they offer less than you need for it politely decline... and let them walk away... they may be using psychology on you... however, if you really are desperate to sell it tomorrow that is hard to hide... Don't volunteer any of those fix up items until and unless they state them as an objection to buying it....... good luck,,, Greg
