I've got a few local favourites here
Firstly, I have a real soft spot for the XY Falcon GTHO (High Output), the Phase 3 in particular. An unmodified road going version in mint condition you could easily see anywhere between 75,000 to 100,000 pounds. A genuine race-spec version could easily net you between 150,000 to 250,000 pounds. I know a guy who had one from new, but he had done a few tweaks to it and it was starting to show its age. It was also his daily driver. He ended up trading it in on an FG Falcon XR6 Turbo 50th anniversary, plus 20 grand cash, which he spent on tarting up the motor
This one is the Falcon F6 Typhoon. Out of the box it comes with a 330kw turbocharged 4 litre straight six. I've seen some examples push 1,000+ HP
And this is the F6 Territory. Its an SUV based on the Falcon platform, again equipped with the 330kw straight six. The latest Territory comes with a 2.7 TDCI taken from the last model Land Rover
There's also the F6 Tornado, which is the Falcon ute with the same motor. Get ready for some extreme slipping and sliding fun.
