1980 cadillac eldorado biarritz diesel

True barn find 1980 Cadillac Eldorado Biarritz diesel. This car has every option and they all work power doors,windows, and seats sun roof functions but needs the weather stripping redone it does NOT leak but is weathered pretty good. The headliner needs redone also it sages a decent bit. Runs and drives and rides like a Cadillac! The air ride works and works good I live down a dirt road and the car feels like your driving on pavement. The car fires right up after letting the glow plugs cycle. The one known problem that it just started on me and my daughters last drive was a fuel leak it looks to be leaking at the throttle shaft. The local diesel shop said they could reseal for a couple hundred bucks it doesn't affect performance but does leave drips when running. The previous owner said the car has set for years. The tires are about 40% and weathered I drive the car locally with no worries but would put tires on before going cross country. The only things I have done to the car is put new batteries, service and fuel it.
