my father in law is selling a red 99 lightning with 63000 miles. he just replaced the driver side head due to the head spitting out a spark plug. it does have a rebuilt title. i think it needs a torque converter cause it makes noise while idling. i checked the frame and everything looks clean it appears to me it was hit on the front end cause the hood and grille appear to be repainted and cheap aftermarket parts. he asked me for $7000.. you guys think that's a fair price being the truck is a rebuilt title? what would be a good offer? any suggestions on what to check before making him any offer?.....thanks
