No, not idiotic, Greg. Here are a few thoughts from a life long northeastern car buyer.
1. There are many owners here in the rusty northeast that do not drive their cars when salt gets applied, even non-collectible modest ones like a J30, Maxima, or Miata. Heck, I know of an old 350Z in PA that's seen snow just once, and it has it's undercarriage cleaned regularly anyway. And cars like that get sold all the time. The 2 keys are patience (which you have but Nala lacks), and looking underneath (something you would obviously do, but not a naiive untrained kid like Nala).
2. You're not factoring in all costs/risks for buying out of area.. Many folks want to see/test drive the cars in person before committing the money. So in addition to the cost of the vehicle and its transportation costs, you're also talking about potentially hundreds of dollars in transportation just to see the car, (airline tix, hotel, airport parking, food, car rentals, gas, incendentals). So if we're talking a cheap rust free DD in New Mexico to use in CT, you could be literally talking up to double the price to do it. Is that worth twice the price? Debateable, I suppose, but many folks would say no.
3.Now, think about if there's something significantly wrong with the car not mentioned in the ad. A car can have other issues besides rust. And if you fly out to check it out, you could be out hundreds of dollars for a wasted trip if it turns out not to be as advertised. And you're not gonna be able recoup that cost/time from the seller. So if your'e on a budget, it's far less risky to take your time and seek something locally, especially in the northeast which is densely populated, and therefore lotsa inexpensive cars around for sale. They're not all rust buckets.
Of course, if one is well connected, he/she could have someone they trust there that knows what they doing, willing to check it out closely for them. But in reality, very few people have that luxury, much less willing do that for free.
4. I also question whether it's that cheap to transport a vehicle from the southwest to northeast, which is traditionally considered a "front haul" market, as compared to the reverse which is normally considered a much cheaper backhaul market. Though I admit I do not know if car transportation follows the same pricing trend as general freight.
If we're talking buying a collector car, I can almost see doing something like that but only under the right set of circumstances. But remember, this case involves Nala, who (a) is much more likely to wreck a car before it succumbs to rust, (b) who can't turn a wrench or drive a clutch, and (c) can't even
afford a second car in the first place, much less fix it up. Don't forget his parents are still supplying his primary transportation.
