That's interesting Mark - I am slowly compiling the MGF rot hot spots, as I think I need to up date the guying guide that says "MGFs don't rot" - when clearly they do! But down south, and particularly in the south east, MGFs don't - which is more a reflection of the climate than anything else.
The front wing always seems to rust out from the inside above the bumper mounts - it appears that moisture gets trapped where the panel is bent over, and there is over-lapping steel spot welded together.
The side repeaters seems to attract rust - I presume this is down to paint damage from the indicator units.
The sills rust over that seam - which is largely down to stone mediated paint damage.
The air intakes rust, seemingly in the same place to the rear of the apperature - more often on the nearside than offside in my experience, but it can certainly effect both sides.
Boot lids rust along the seam either side of the high level brake light. Was this the case with 'your' TF?
I haven't found much in the way of structural rust yet - but note Matt's recent experiences on his car, and evidence of rust effecting the floor pan in the rear corners adjacent to this area.
Subframes rot - I've found rotten front and rear subframes on Project Shed (not necessarily from the same car I hasten to add) - and of course, there is that other favourite rot area - the front lower wish bones.
So quite a lot to look for potentially!!!
BTW, the responses you've had are hysterical!

Probably not unexpected though - I guess the vast majority of car owners are not car-literate!
Would definitely like to see you compile the 100 "best answers" to a car buyer's question!
