Ford Coupe Range

1350 units of the second generation Ford GT were be assembled at Ford's facility in Ontario, Canada, while 4038 examples of the first generation were built.

Even if you could get the radiator from a Focus (and you haven’t told me what year Focus) a radiator designed to cool a small four-cylinder engine probably wouldn’t have the capacity to cool a larger, V6 engine as found in a 2002 Ford Cougar. Perhaps it would work at moderate speeds in cool weather, but a freeway drive in high ambient temperatures would very possibly see it fail to cope. You’d also need to ensure that the radiator suited the transmission fitted (a radiator for a manual car can be different to one for an automatic).

From what I can see, the radiator to suit a 2002 Cougar is, in fact, interchangeable (on some level) with that of a six-cylinder Ford Falcon from 2002 to 2008. Perhaps that would be a better idea, but I’d still be running a tape measure over both cars and taking careful note of where the mounting points are. Or, simply buy the radiator that’s designed to fit the Cougar.

There’s clearly no point in talking sense to you, your head is in a complete muddle. You want a fix for your mid-life crisis, yet you talk about resale value, warranty, fixed-price servicing and boring stuff like that. You need to think about what it is you want from your “sporty-ish” car, do you want a performance car that will be thrilling to drive, or are you a park-and-poser and just want to look good when you stop at the café for a latte. The VW Golf GTi is a thrill-a-minute hot hatch; you like the i30N, and both would be good buys. Buy the Lux if you decide on the i30N. You could also think about a BMW M3, or an older Porsche Boxster. I wouldn’t suggest a Commodore SS or a Falcon XR6T ute, they’re a bit boring.
