& they'll be able to tell you how far off it is. Other stuff to look into: 1. title = clear, salvage(ie. branded) 2. Realistically assess your financial ability to support this Z. If you inherit a problem Z it could end-up costing you 100% more(or even higher) than what you buy it for(especially if you aren't a DIYer on major engine/mechanical stuff) so include that in your assessment. 3. If the frame is out of whack it could result in poor handling/pulling to one side, &/or premature tire wear(more $) OR it could be minor & you'll never notice it being off 2/16". There's an FAQ(a voted one) that does a good job of listing things to look for when buying a used z. Good luck!
