The tires still have air, the battery of course is dead although while it was being used, it was replaced with a Die Hard. What would you suggest in order to get this car running and start using it?
You didn't say if the Diehard was a sealed battery or not, it it'* not top off the electrolyte level with distilled water and see if it will take and hold a charge, If not, pop a new battery in it, check the oil level, and see if it will fire. If so, fill up the gas tank with the appropriate octane fresh gas and put anywhere from 50-100 highway miles on it, with that low of mileage you shouldn't have any suspenion issues or such, but more than likely the tires will be flat-spotted and you will have a thunk-thunk noise from them and feel it in the steering wheel. If the tires have no weather checking on them they'll probably be ok after you put 500 or so highway miles on them. After the afore-amentioned 50-100 miles highway driving, oil and filter change is in order, after that change out the Dex-Cool and check the transmission fluid dipstick, after only 12k the trans fluid should be ok for awhile, but as soon as feasble do a tranny pan drop and filter change and upgrade to Dex VI, they used the Dex III until 2006 I believe. Good Luck!
