Yes and no. Yes because a car like that will probably be worth a small fortune in 10 years time (assuming its kept in mint condition). No because if i was a cashed up GTR enthusiast who wanted a prime example of an R32 Godzilla, that car would be the perfect buying opportunity.
The GTHO didn't cop this much notorious criticism and negative media driven backlashings? If i remember correctly the GTHO Phase III caused such a public outcry that ford decided to end development of the Phase IV and all subsequent Phase GTs.
If anything the Phase 3's notoriety is what makes it the collector's special it is today.
The following quote is from drive.com.au:
"The original 1969 GT HO was powered by a 5.8-litre V8 and was claimed to reach 100kmh in just 6.4 seconds, making it the most potent Australian-made muscle car of its time. However, by 1972, controversy about road-going race cars killed the GT HO Phase IV program before it hit dealerships."

Trust me, in the long run original well maintained GTRs of any example will be worth more than we expect.
