Alex i can see your point 100% - but on the matter of bady parts/repair panels it will always be a case of cant please all of the people all of the time no matter what the cost or quality.
People are really quick to knock the quality/fit of pattern panels - mind you think Jonothan said recently that they were getting thinner which is a poor thing.
Lot of people forget that even on modern cars you get a pattern panel from the factors and it in all likelihood will be a poor fit and need some adjustment (not to mention thinner than your Grandad's combover

) .
Would imagine that even when these cars were being produced on the line there would have been a certain amount of fettling going on - I mean come on were not talking Aston or Roller of old kind of coachwork.
Even with genuine NOS panels shouldthink that very few of our cars have spent all those years unscathed, few dings, bit of distortion here and there so in some cases a NOS perfect panel might be showing time related imperfections on the car itself.
Frank as for the chrome - it seems to be the general concensus that its really poor.
Right I just got off the phone with my favourite parts supplier Bull Motif
15 minutes talking about chrome & parts in general.
Some interesting facts - chrome manufacture is not the same quality accross the board due to the manufacturing process being changed due to H&S regs !
BM do however strive to get the best available and guarantee it for 2 years.
Interstingly - why dont modern cars get made with chrome on? Because mostly it will fail through time.
Live by the sea? In a city? Near an industrial area with high polution? Keep polishing new chrome with abrasive cleaners?
(i know we have someone who works in a chroming place on this board so hopefully he might be able to add some wisdom to the matter)
Seriously guys ended up talking about this subject for some time and its blatantly clear that they take quality very seriously - after all they stake thier reputation on it. Sourcing new or better parts is hugely expensive for them but its an ongoing process.
As a sidenote too its blooming lovely to be able to phone a company and get all the info you want about something without buying a thing, dispelled my belief that customer service isnt complately dead !
