Evoke,
you can only do your best with inspections.
I bought mine from a Maserati Indie in Kent and arranged to have the inspection carried out - all easy to arrange (I used the RAC - very good).
The dealer agreed to put right the few small issues but later I found nothing had been done.
I found out as they used a neigbouring respected workshop for Maseratis, and the boss rang after the furore caused by my postings on the other forum.
He told me that the dealer had NOT instructed him to correct the faults.
So the suggestion is that
1) Yes you must have an inspection
2) Make sure that the work found is carried out or
3) Walk away if there is anything major found - we know of some who had major issues with major faults.
It's worth the peace of mind for around £250-£300.
Oh and, I have the car, it's now in decent order, thanks to Emblem of Poole.
...and I love it.
