I would take the new clutch as a positive.
The clutch on the Evora is a known common issue which is exacerbated by the amount of labour required to remove the rear clam, engine etc to replace it.
I was advised when looking for an Evora that I should budget for a new clutch if there was no evidence of a replacement, admittedly, I was looking at S1 cars older cars rather than a 400 would be, however, the advice proved to be spot on as the clutch needed to be replaced pretty soon after I bought the car but since I’d factored this into my purchase, it was an expected expense so had already been factored into my decision to buy.
As an aside, my clutch lasted 125,000 miles due mainly to the fact a previous owner did the vast majority of the cars miles commuting/cruising on a motorway so not really straining the car at all. I’ve not heard of any other Evoras clutch last this long so this appears to be an exception, rather than the rule.
My car is a 2010 car, coming up for its 10th birthday this month; I’d be interested to know how long other folks clutches have lasted and how many miles they to covered in the process.
