Hi folks,
I can easily see it as Got Rice and a13... see it. But I can also see it the OP sees it since value is a highly subjective call. In the universe of cars, Camry constitutes a rigid, front-heavy FWD box connected by macpherson struts to four wheels. As I've written on several occasions, on good street tires, this package will only go about 5 sec in the 0-60 under the best of conditions. As I've also written on several occasions, the more engine output increases, the more the drivetrain favors a shift of mass rearward, and RWD. Therefore there is not much to be gained in performance with a Camry, before you hit several aspects of the brick wall represented by an FWD format.
For me, the biggest bang for the buck in a Camry from a standpoint of, "Let's see how much fun we can get out of this car," is in the area of handling. As I've said, handling is something you feel in a car every second you drive it, while a powerful motor makes its presence known only every once in a while (well, unless for you, every street light is a signal for a drag race...).
If, for you, "fun" is going faster than about 5 sec in 0-60, then Got Rice and a13... nailed it: you need a different car, and it should be RWD. But such a car could cost north of $40k. Plus insurance. Plus maintenance. Plus space to keep it.
So dialing this back to a much more modest enterprise, where, let's say, a few k$ may be on the table, and you want to drive/insure/keep just one car, then doing some modest things with a Camry may constitute good value after all.
Ultimately, value, like beauty, is in the eye of the beholder. Me personally - I would follow Got Rice and a13...'s advice, and find me a good '60's-'80's chassis from Detroit, and redesign it/rebuild it from the ground up, as I've done on several occasions.
Nothing in a Camry could hold a candle to the fun and satisfaction one gets from doing that. But life's short, and not many people have the time and money to go down that route, so most do what they can with what they in front of them, even if it's only - yes - a Camry
Oh and, btw, coming back to power-adders and the theme of economy, why not nitrous?
HTH,
Mark
