I have owned a '71 competition stripe, a couple of CIJ reissues from late 90s/early 00s, and a newer US P/J Mustang
Of the three model types, the new US one somehow felt sterile and lacking in character and I sold it on quickly. In all truth there was not much between the '71 and the CIJ reissues, either in sound or playability. The '71 had bag loads of character from the ageing/mojo and a lovely deep thump. I sold it on as I bought a shiny new toy (a Serek short scale) but regret having done so (and have since asked the buyer unsuccessfully if he would sell it back to me ...)
Comes down to budget. If I had a spare £2k I would buy a pre-72 Mustang (thinner neck, lighter weight than mid-70s Mustangs) but if I were more budget constrained I would be more than happy to buy a good condition second hand CIJ reissue Mustang.
