Both are excellent cars. Go for the Camry if you want less expensive repairs. 

Condition, a big factor in any purchase ! Get it checked-out before you even have morning coffee !

Then, which has the higher current market value ? No-brainer, right ?

The Lexus has more marketable features and comfort, Camry is basically "plain-jane".

But also consider historical cost-per-mile data (available from several sources), which considers lots of factors prior to providing a final result. And try to find out how the vehicles were previously used ! Any wrecks, clean title, city or highway use, used in a snow environment, or in a dry, no-salt area. There's lots of factors to consider.

Only after all the results are in, can an objective decision be made, right ?

Almost the same thing. GS has more luxury and electronic features, which can fail down the road.
