There was a prestige dealer near me , he had 2 DB9s in , both silver but 4-5 years between them , I can't remember the figures but there was a lot of money between them
I'd have had them well seperated because all I could see was the newer one was going to cost me ££££ in depreciation judging by what the older one was up for
TBH given the risks I'm surprised anybody retails old cars anymore especially ones where a door seal costs £1000
