Re: Vette to Crossfire?
A base C5 is faster than SRT-6, high 12's low 13's @107-109 is not uncommon. A C6 is faster than a C5, They have gone 12.3's@114 stock. TQM is the key to them.
A C5 Z06 is faster than a base C6. Low 12's high 11's are yours if you can drive. Mph around 116-117. And we all know the C6 Z06 eats vipers, so the SRT-6 doesn't stand a chance in hell against that. Then you add mod for mod, its over for the SRT-6.
Now back on topic.
There is no chance in hell I would trade my Corvette for a XF. Even for a SRT-6 let alone a base. The power in the base XF is lacking, and led me to buy other faster cars while keeping the XF, because trading it in was not an option due to the XF holding its value like a Taurus.
What are the specs on your C5? Miles, options, etc.
