lol well to the OP, like I said, Fords have sucky depreciation, and the build quality is bad (found out the other day that you can't service the auto in the BA, you have to rebuild the bloody thing at 150 000km, don't know if this was rectified in later models).
In regards to straight line power, I have seen a lightly tuned HR31 Passage w/ NEO HKS 2540 stock Stagea ECU and the usual FMIC, EBC and exhaust, beat a Force 6 with a flash tune and exhaust, mind you a HR31 weighs around 1300kg not 1500.
XR6T would probably be the pick of the local product, but for me the build quality issues that Fords always seem to have would push me in favour of a Commodore (LS series motors FTW!)
The V8 is definitely not dead - I've seen more VZ and VE SS on the roads than just about any other model lol
