Yeah, I run a Storm VR6 - they don't have air con btw, that's just wrong, one or two might but generally the Storm just has a standard engine, heated leather and is a limited edition in two colours.
Love mine to bits, the VR6 motor makes great noises and goes quite fast if you rev it, not as quick low down as you might suppose though - Schrick variable manifold reckoned to be the answer to that. Does around 28mpg cross country driven briskly and around 35mpg on the motorway at fastish speeds.
General issues? The bodywork is galvanised, so should be rust-free unless pranged or neglected. The cooling system gets a caning because it's a big old motor in a small engine bay so runs hot - thermostat housings crack and hoses sometimes split. The ideally wants its chains and tensioner changing somewhere around 100,000 to 120,000 miles and rattles if not, though a lot of this may or may not be an issue, I've not heard of one snapping, but they get noisy and the tensioner pad wears away. Sun roof mechanisms are made of pot metal and snap, fiddly to fix, the spoiler thing control unit goes sometimes so the spoiler won't go up and down.
You have to remember that even the latest ones are now 1995, so around 14 years old, so some things are just dying because, well, they're old. Coilpacks go and cost about £100 to replace, makes the engine sound like a Scooby as they run on four. Rear brake calipers can seize, like on a Mk 2 Golf GTi, just replace with reconditioned Golf Mk4 ones. Clutch slave cylinder wears with age. Second gear synchro is a tad weak and can go with use.
If it's still got the original suspension and steering bushes, they'll be well on the way out and getting the car re-bushed will make a huge difference to handling.
Really you need to buy on condition, try loads of different and, preferably, find one that's been enthusiast owned and looked after, possibly upgraded.
best place on the web for corrado information is the Corrado forum which is arguably the friendliest, most useful forum I've come across. There used to be an excellent buyers' guide in the Wiki there, that's well worth downloading and printing off as a reference.
Anyway... brilliant fun to drive, still nice and visceral, bodywork and some specialist parts expensive cos they're one offs, but lots of other stuff not so bad and lots on eBay and on the C forum. Yep, there are faster modern cars etc, but it's not really about that. And there's a nice stealth thing going on where most people don't really know what the car is. Lovely
