For the guys that bought 12 or 20 of the 20 million credit cars, my question is why? (Please answer something other than "why not?")
If it's a car you use for racing online, it can be necessary, depending how competative you are.
The Lambo Muira is really good around 500pp. If a person decides to make the Muira one of their main horses, they will run out of settings sheets very quickly.
-a short circuit setup (shorter transmission)
-a long circuit setup (longer gearing, maybe lower and stiffer, as most GP style circuits in GT are very smooth)
-a short road/street course setup for tracks like Matterhorne, Madrid, Eiger, etc. (again, shorter transmission, but with softer suspension to handle the bumpier surfaces and curbs.
-individual setups for the big tracks like Nurb, La Sarthe, Sierra, Bathurst, and even SSR7.
-a person might want a stance/cruising setup to enjoy cruise lobbies.
-technically, it would be ideal to have a wet weather version of each of those variations I mentioned above.
So, that's roughly 15 different setups, for one car, at one PP level, on one tire compound!
Also, a person may want to experiment with buildings high power / high weight setups vs low power / low weight. You can also come up with different builds based around either high torque or low torque. This type of variation with builds is actually the most troublesome, as when you start swapping parts around, you can really mess up your tune. There's nothing worse than spending 10, 20, 30+ hours working on tuning a transmission, only to have everything get 🤬 up because you swapped a part which changes the redline.
Based on what I regularly see online at 500pp, SH, SS, and RS are the most common tire compounds used, with SM and RH popping up from time to time. So if you want to get serious about things, we had 15 setups, multiply that by the 3 common tire compounds (or all 5 if you want to get really crazy) and we're now up to 45 different setups, for a single car at a single PP level.
So in theory, a person would need 15 Lambo Muiras in their garage to accomodate all these various setups.
If you want to use that car at different PP levels, say at 525 and/or 550, the number of setup sheets and cars required multiplies again.
I realise this is taking things to the extreme, and there's probably not many people who do this...but at the same time, it's a legit reason to buy 20 of the 20mil cars.
For most cars that I use often, I have about 10 copies of the same model on average.
Like I said, I only used the VGT glitch a couple of times, and basically used it to buy and upgrade 90% of the RWD cars in the game when GT6 released so I could get maximum enjoyment out of playing online when the game was at its peak. Now, I keep about a 3-5mil float by staying on top of the seasonals, but I find even that to be annoying.
Due to knowing that I don't have the funds to really build a stable of Muiras or GT40s, I don't even bother looking at them, and to me, that's a shame.
I can't really describe how much more enjoyment and sense of accomplishment I get from honing my racecraft skills online (completing a clean pass or block), tandem drifting with friends, or shaving a few tenths of a second by tweaking a tune, than I do from grinding credits to gain access to some polygons.
