I really suspect you've got a better car, but the CVPI...I dunno. Body on frame, RWD, pretty nice engine tone (even if they're starved for performance).
I wanted a RWD car for the sake of transmission maintenance. Simple stuff becomes a LOT more complex when the transmission is hanging out the left side of the block. Unfortunately, I could not get one in my price range. Thus, I got what I did and put up with it.
First off, the CVPI isn't as built up as the Marauder. They make it up by being a more reliable Crown Victoria. The engine being starved for performance would seem to be an issue of them trying to fit environmental regulations into one of the last (mass produced) body-on-frame RWD V8 cars out there. Should I ever find such a car and have the funds, I'd gladly buy one.
That said, my car isn't too far off from the Crown Victoria in how it is built.
My Aurora is about the same way with the engine - a largish Short North V6 as a part of a ~3600lb package. Ironically, it is spec'd to have a larger gas tank at 17 gallons if I'm reading things right about the options. Flooring it is not an option that will work as it should, but it
does give a satisfying engine note. It is made more for long trips, and the performance / MPG ratings show it.
The largest mistake they made was to use the 4T65E which was being pushed to its limits. For the ones on the road (like mine) that don't get the 4th gear redone with a hardened part, it will literally eat the 4th gear teeth. It is not a performance car, but the 4T65E was not really meant for such loads as designed. Oddly, this fixed part ended up on later Regals first IIRC, and at least it is a solid fix.
Look up the specific issue if you're that inclined. Or go to a junkyard and wonder why the 4th gear is gone on this part. Then pull out the part you wanted to get in the first place.
