I think 30% is an exaggeration. I think its more like 15%-20% and GT5 is close to 50%. No question GT5 has waaayyyy more duplications.
I did say if the same standard was applied, because the list that rate GT5 as close to 50% dupes does class a good number as dupes that are not.
Once again its down to both defining dupes and applying the exact same standard to both, and unless that's done then the number are not worth a damn.
Just wanted to make a quick correction Scaff. The 911 RSR is a different animal than a GT3 Cup car. A lot of the models were probably reused aside from new bumpers/spoilers and the widebody of the RSR. I'm sure some reusing of model bits were done but they are different cars. 911 GT3 is an S class car whereas the 911 RSR is an R3. Power and weights are different too. In both examples they have some duplicates like you mentioned. GT5's list though has WAY too many Skylines, Miatas, 3000GTs, RX7s, etc and everything about them is the same. Most have same weight, power, torque, everything really and only bits that are different are color, year or some special edition of some sorts. The car is still the exact same padded one. I mean look at how many Miatas and Skylines there are and most aren't different models at all.
Which is why I said.......

It could be argued that the above is actually 5 clearly different cars, rather than the 18 listed.
...so
911 GT3 Cup
911 GT3-RSR
F430GT
FG Falcon
Commodore VE
Which is five clearly different cars, as I already said.
However some of the logic used in the GT5 50% list would have seen all the 911 race and road cars put together, which once again comes back to a standard for what is a dupe and applying it equally.
Take for example this entry from the 50% GT5 List
Honda S2000 ‘99
Honda S2000 ‘01
Honda S2000 ‘03
Honda S2000 ‘06
Honda S2000 (EU) ‘99
Honda S2000 (EU) ‘03
Honda S2000 (US) ‘99
Honda S2000 (US) ‘01
Honda S2000 (US) ‘04
Honda S2000 Type V ‘00
Honda S2000 Type V ‘01
Honda S2000 Type V ‘03
Honda S2000 Type V (EU) ‘00
Honda S2000 Type V (EU) ‘01
Honda S2000 Type V (US) ‘00
Honda S2000 Type V (US) ‘01
Mugen MUGEN S2000 ‘00
Opera Performance S2000 ‘04
Spoon S2000 ‘00
Spoon S2000 Race Car ‘00
While it does quite clearly contain duplicates, it also contains a number of cars that are also very different, with a mixture of first and second gen models, performance variants and a race model. Were I to apply this same logic to the 911 list above it would both validate keeping them all in the same list, adding in two generations worth of 911 road car and then calling them a single car.
Thus my point about equal standards.
