San Jose psychologist Charles Preston says the cellophane-wrapped cocaine was found when he took the van to a mechanic to get his brakes checked.
Police were immediately notified.
The San Jose Mercury News says Preston paid $14,000 to Thrifty Car Sales in Santa Clara for the 2008 white van in May 2010.
Preston says he noticed the driver’s side window wouldn’t go down all the way, but he figured he would live with it because the Town and Country van had a good air conditioning system.
Thrifty Car Sales owner Ron Battistella says he’s willing to replace the van with a drug-free ride.
