Old frame with new group does not really bother me and can qualify to porn... PhilPub's Ron Cooper for instance is a really nice example (I believe I'm talking about the righ person / right bike here, from CP)... In the case of that peugeot, it's just that the frame did not appear to me as a very high end one, despite being called "super competition". I'm sure Peugeot did better than this during that era. The other Peugeot DMC Zone posted after already seems nicer (seat post cluster looks like it's a forged one, chromed dropout and chainstay, etc...)
Check the link I posted - if it is a '79 then it was the top of the range in the catalogue, but they did higher end custom order frames (including Reynolds 753).
