Welcome and congrats on the 428 purchase, that's an awesome piece of machinery.
As far as licensing goes I'll mention what springs to mind, someone else with more recent experience might chip in.
Check all the roadworthy things: Handbrake (must hold the car in gear), windscreen washer/wipers, indicators, brake lights, number plate light etc all functioning properly. Dual mirrors (you'll have these anyway I guess), no oil leaks. Standard seat belts will be OK as long as they are not frayed and retract properly. Check ride height. Red flashing indicators should be acceptable.
You need to have an engine number clearly visible and your import approval, receipt of sale etc.
The requirements do vary from one licensing centre to another so it's pretty fluid and experiences will differ.
If the car is unmodified you should be OK. If it has been modified, you may need an engineer to sign off on it.
One more thing - How about some pics!
