I think you will find that the wiper motor/clamp/tubes and wheelboxes is a standard buy, as a kit, from Car Builder Solutions (CBS)
I have a boot lock with keys (as shown in the picture) still in the packet from DNA, that I didn't use...not sure how much it's worth (its probably from CBS as well so you could probably find the price of it on there)
I also have a hydro chromed replica 3d printed boot handle with fitted fake lock... and a 3d printed boot handle with no lock (the latter I bought as a spare before I forked out for a "real" one (a whopping £355 by the way!!)....both for sale....however please bear in mind that, should you wish to make an offer, for the bare 3d print alone I paid Brian £60...the lock in the chrome one cost me £25, plus chroming on top...so my (not very subtle) point is that this stuff ain't cheap!
I don't want to make money on anything...just somewhere near to what I paid for them.
Count Arthur Strong once sagely said about the programme "Wheeler Dealers" ;
"Its a telly programme where they buy cars, spend a fortune doing them up, and then celebrate selling them for slightly less than they paid for them in the first place"
