Another dealer said a new 4/4 would not be able to cope with daily use (eg 25 miles a day every day plus half a dozen big trips a year; total annual mileage about 8,000)...
Not a

It's a car and designed for only one thing. As has been said elsewhere on here - use it. If it breaks, repair it; when you are tired of it, sell it. Above all, do not keep it in top notch condition simply for the benefit of the next owner.
