I used to think that a V6 wore more slowly and thus lasted longer than an I4, but it's not actually true. The V6 is normally under less load in proportion to its maximum output, but that does not necessarily mean that it's being worn less.

The design of an inline engine is inherently more reliable than a V-type engine not only because of fewer parts, but also because the crankshaft is supported by an extra bearing. This makes the inline engine structurally superior and normally run "smoother" than a V-type. The old Lexus I6 was about as good as an engine can get as far as quietness.

Sometimes, the repair costs are much higher for a V6 engine because it takes up more room in the engine compartment and thus takes much longer to complete the same job.

There is nothing wrong with the Camry's V6, it's not measurably less reliable than the I4. But for the OP, it doesn't add any benefits for the extra costs (gas and repairs).

Also, I agree that $6500 for a 1997 Camry is too high. That's how much I paid for a 2000 Camry recently (although with about 4X the mileage).
