so i'm about to buy this 300ZX and i check out the carfax its clean title etc.. but it says "The last record reported to CARFAX is from June 1999. While there haven't been any DMV-reported problems, check with the seller to see if they have any service and repair records before you buy. " The guy who i'm buying it from said the car he bought from a buddy and owned it for a year now or so.. but theres no history.. also the last known miles is 95,000 in 1999.... the CAR has 89k...? whats going on here? this is the first time i'v used carfax before
