Can't argue with that.
Considering how many V10 are on the road, don't forget E and F series trucks and Excursions, the engine appears to be pretty reliable piece of hardware. Maybe not to the point of the old VW air cooled flat 4 but nowhere even close to the rolling disaster that GM attempted in late 1970's with a V8 diesel.
Make an offer and see if they'll either counter or accept. If the offer is refuse leave your contact info and tell sales staff you're ready to negotiate when they are.
