Thing is all these cars are very rare and there is a huge demand - hence the mad prices for original cars at auction. Jaguar and now Aston Martin have seen an opportunity to both raise their profile by building these copies/recreations/continuations.....call them what ever suits your opinion, and also make a few quid into the bargain.
Can't see Ford making Model T's any time soon - most people could not drive them - although I do recall reading somewhere that Ferrari were supposed to make 100 250GTO's for homologation purposes but they only ever built 39 or so. Who knows...given that Talacrest is selling an 250GTO for a rumored $55 million maybe Ferrari will knock ot the remaining 61 cars for a bargain £5.5 million each..that would bring in $335.5 million and I would imagine they would sell in hours...
Only the hyper rich can now afford some of these exotics but there are plenty of merely super rich who want to get their hands on one so watch this space...Aston DB4GT's won't be the last.....although the Earl of March won't be inviting any of them to the revival any time soon
Mere mortals like me will just admire at car shows...I would not want the responsibility really.
