Well they certainly are very old, see below registration history. The 732s (you can spot them by the cigarette shaped narrow engines) are like what the original volkswagen beetles are to cars. They're everywhere in emerging markets, they do run if they're maintained well, but with a startup in peru flying 30-ish year old planes that have been operated by half a dozen operators in the past at least I don't feel comfortable..

http://www.airfleets.net/flottecie/Peru ... e-b737.htmYou can check stats for accidents here:
http://www.planecrashinfo.com/database.htmOne would have to look very close to see why each of the 737 accidents happened, but there are a number of older ones involved (though don't know as percentage of stock of each type of 737)
My point is, these guys may very well be safe, but they have no track record and their equipment doesn't make it any easier to believe that they would be safe, because old equipment requires very diligent service. For example, would be great to know where these guys send their planes for service. Someone like LAN and other big airlines send theirs to a few well-established and regulated international service centers. Peruvian airlines? Don't know, they could be sending them off or not (i.e. do in house), again we don't know.. why take the risk?
