My Mussy (65 coupe) only owes me about $12-15K.
I bought it in the states, (US$3K), shipped it full of parts, put a new 5L roller reco engine and replaced/rebuilt almost everything mechanical, new interior, wheels etc. I now drive it (well for another couple of weeks until rego runs out, as I have to buy a family car) with the dodgy flat black dented bodywork it came with, and it is a reliable daily driver. All it needs is the body/paint work done.
But then it will owe me about $20K. Mind you I did 90% of the work myself, so if youre not mechanically minded you can triple that figure as labour is the big killer.
