Not sure why anyone 'takes sides' and why anyone would be laughing at anyone else?
JLR or any large scale business who develop, manufacture and sell anything has to accept that competition will always be there and they need to invest in their products to keep them the top choice.
Lucky Lucky Rolex are not a comparison, they boil my piss and Rolex don't stress over them. They have eyes on their quality competition, not the cheap Chinese shite people buy.
If the Jaecoo, or anything else is worthy of a second look, good on them, but I do think they will sit as another option and not close down JLR.
But these threads barely offer any logic, so who am I to have a sensible opinion...
