I'm looking into buying a 1999 New Beetle 1.8L Manual Transmission. the seller is selling for 2300, It was 143,300 miles on it. He says there is an electrical problem where the car stops running while driving sometimes but he just waits and then turns it back on and it works.The battery is new so it's probably not the problem. he wants to get rid of it for a Truck so hasn't bothered to see what the problem is. What's the worst this problem could be? I'm not looking to spend more than $1,000 in upfront repairs.
