Carnac the Magnificent Mechanic

 Anybody remember when Johnny Carson would be Carnac the Magnificent? He would use his power of mind to answer a question before seeing the question. Always funny.

In a similar vein, I'm going to take a look at some information I have on a car that I have not seen. For instance a random car for sale online with a vin 2C4RDGCG7DR798845. 2013 Dodge Grand Caravan with 128,277 miles. 

Alldata tells me the van was serviced and battery replaced 7/10/25. Alldata also shows a technical service bulletin related to a flash update to the fold and stow module to address a problem with the module sometimes staying in wake mode and discharging the battery.

ShopKey Pro charts the mileage of battery replacements on these vans, easy to notice the peak times to expect a battery failure. 

Based on mileage we can also expect it needs brake pads and spark plugs unless they have recently been replaced. It is also worth noting that 128,000 is the peak mileage that a timing chain is often needed. Good things to bear in mind when you are shopping and considering this purchase.
