User blog:Eth3792/Cost analysis - v7.1.5

Introduction
The IMSA GTD Update (v7.2) adds four 2018 GT3 cars: the Acura NSX, the BMW M6, the Ferrari 488, and the Lamborghini Huracán, as well as new IMSA GTD series in 2018 Season and IMSA GTD Exhibition. This should be another light update cost-wise, as the four cars are identical PR-wise and (presumably) only one of the cars will required to 100% the new series. Excluding the new cars, the highlight of this update may be new Exclusive series for two older cars, the Hennessey Venom GT and the Mercedes-Benz CLK-LM. Some terms used in this post include:
 * Immediate bonuses: Bonuses immediately attainable after earning the car at LTS (or SE) upgrade level.
 * Short-term net: Net cost of earning the car with minimum PR. (LTS rewards - cost of upgrades + immediate bonuses)
 * Completion bonuses: Bonuses not attainable with LTS upgrades, but attainable with less than full upgrades.
 * Completion net: Net cost of earning the car and attaining said bonuses. (Short-term net + completion bonuses - cost of extra upgrades)
 * FU bonuses: Bonuses only attainable after fully upgrading (e.g. Exclusive Series).
 * FU net: Net cost of completing every event this car can complete alone. (Immediate + completion + FU bonuses - full upgrade cost)
 * Future bonuses: 100% bonuses for which this car is just one of the required cars.
 * Long-term net: FU (or completion) net plus future bonuses.
 * Net discount: How much you save by earning the car through an LTS or SE. (cost of the car + LTS/SE rewards)

New Cars
====Acura NSX, BMW M6, Ferrari 488, and Lamborghini Huracán GT3 Championships==== Cost-wise, there's not much to go on yet as the cars and series have just been officially announced. We do know that 2018 Season will pay 75 for 100% completion.
 * Minimum cost to finish: -???  (PR 79.5: 3333333?)
 * LTS rewards: 100, and either Acura NSX GT3, BMW M6 GT3, Ferrari 488 GT3, or Lamborghini Huracán GT3
 * Immediate bonuses (?? ):
 * 2018 Season: ??  (??%)
 * Short-term net: -??? 
 * Completion cost: -???  (PR 82.3)
 * Completion bonuses (?? ):
 * 2018 Season: ??  (100%)
 * Long-term net: -??? 
 * Car cost: -750
 * Net discount: -???  (??% savings)

Series-wise, there's only 2018 Season and it will probably stay that way. You can also earn 10 from IMSA GTD Exhibition (note: uses only the Acura), but this can be done for free anytime.

Car-wise, there's a lot of hype for these four cars. We'll have to see if they live up to their real-life counterparts!

Future-wise, there will be a WTTT for the new GT3 cars in a few weeks. Iinterestingly, all four will be loaned, and I expect to see all four in group A (depending on exact stats and track). Chances are there will also be an OMP round for these four in a future update, but other than that, we probably won't see much more out of these cars.

Exclusive Series
v7.2 brings two Exclusive Series for two older cars:

Hennessey Venom GT
The legendary Venom GT has been in the game for nearly two years, and has been used in more than a couple WTTT and OMP rounds in that time. The 30% sale at the beginning of last update may have been the last chance to get this car for less than 950. Hopefully we'll get an LTS for it in a future update!
 * Cost (from scratch): -950  purchase, -995  upgrades
 * Rewards: +100

Mercedes-Benz CLK-LM
The fourth Motorsports car to recieve an Exclusive Series, the CLK's ES pays similarly to that of its 1998 rival, the Porsche 911 GT1-98. The car was available in a SE last July, so it's a good candidate for a future flashback (if we ever get them back).
 * Cost (from scratch): -640  purchase, -660 upgrades
 * Cost (from series 100% upgrades): -245
 * Rewards: +100
