I bought a new 'Jaguar Land Rover Classic' bonnet and had quite a few issues with it.
The head lamp chrome fastener captive nuts didn't line up with either an original chrome bezel or the aftermarket ones?
Then the side light cluster, on one side, wouldn't fit?
Then the closing catch captive nuts were in the wrong place and had to be moved.
Apart from these problems, it was fine!!
I do find it hard to understand why they don't have a jig for these discrete items that they can fit up to check that fixings are in the right place. Its not rocket science.
So my £10,000 bonnet ended up costing me considerably more for all the extra fettling. Not to mention the fitting and trimming costs which are expected. The company I used for doing the work were exceptional. Unlike the muppets making the bonnets. A little effort by BMH and some quality control would be nice.
After all Jaguar wouldn't get away with it for their modern car panels.
As you say 'captive market' and its better than nothing, that's for sure.
