ok well then i guess to me it would depend on price.
yes you may have the same in it as the c5, but i know how you are.. and im the same.
when you buy somethgin you look at resale value.
the c6 wont have much of a resale being salvage title.
weigh your options
c5 pros : can drive it now, dont put any money in it, clear title, better resale
c5 cons : not as nice as the c6, less power
c6 pros: nicer car, more power, newer
c6 cons: salvage title, more money into it, bad resale, a year before you can have it on the road, may get tired of doing the work, may be more money into it then expected
