The 3.0 and 3.2 are nearly identical, and suffer from nearly the same issues. To rebuild the 3.0 is expensive these days (but still fun!). If you didn't do the rebuild yourself, then who knows what's actually in the 3.2 as well. It's really a crapshoot. Also, you'll have to update your car to run the 3.2 Motronic system, which is not too difficult, but involves a bunch of different steps (you'll need a new tachometer that is matched to the 3.2 computer too).

I went with the 3.2 last year. For about the same price you get a better fuel injection system more torque and a little more power. New tach, computer and wiring harness required. Could not be happer, well a 3.6 would be better but not in my budget last year.

If you can verify the work to the 3.2, go that way and sell your 3.0 as a core for $2K or more. You'll come out ahead in time and money, not to mention a more modern fuel and ignition system.
