Whats it worth???

[ZR1OUS 94]

Hi,
Iam interested in a ZR1 and after having 2 91s back 10+ yrs Iam not in touch with their worth....or good/bad points..
The car in question is a 94 4.5k miles original owner both tops,orig tires ,borla exhaust ,chipped w/original included...Owner says no damage ever, pics look good(Admiral Blue/gray.....Can you give me some high and low values that YOU would pay if you were buying it....What other questions should I ask the owner and do you think its better to wait for a low mile 95 instead? I know AB was a low production color in 94-95 does anyone have one and does it look good in the flesh,lol.....Sorry for the long post but any help would be appreciated before I become a ZR1 owner again.....Kevin
