Good points Alistair, still waiting for your offer on mine - you know it makes sense!
One thing I'd add is that if you've got a properly sorted car then there should be very limited tweaking required. Mine has done a few thousand a year and requires nothing at all beyond an annual service.
The cars themselves are basically bulletproof in terms of all the major oily bits.
Main concern is usually buying a car like this will only 1000 miles or so on the clock, as a several year old car with very limited miles is likely to have sat around without use and that is when they cause owners trouble.
In terms of value vs the coupe / supersports, it's clear that supersports have depreciated more heavily than Aeromaxes - and are now trading a slightly lower prices despite being newer in many cases. I think that makes a strong case for the Aeromax to continue to maintain it's price point for the future..
Mileage within reason shouldn't make much of a difference. Sure if you start putting 20k a year on an Aeromax it will have an impact, but buyers are generally going to look on a 5 year old car (as many of them are coming up to that time) as something to be bought on condition and provenance rather than just the clock number..
