Hello! I have a 81 K5. Last week the motor locked up on it. I still owe $2500 on the truck. My family says that it is not worth it to try and fix it. The back window is broken. The front windshield is cracked. I need new tires. I understand that it will cost a lot of money to fix these problems. Money is tight for me, but I do have another vehicle to drive until my truck is fixed. Does anyone think that it is worth the money to fix it? This is the first problem that I have had with the truck.
