15 Tiers, 45 Events. Open until May 9th. Sometimes the R$ upgrades are enough to get the 25% reward but not this time. Six upgrades = a PR of 87.2. Not enough to run #3.3 which requires 87.6.
Can't find any evidence that Lotus has actually sold any of these cars? Can anyone confirm? Maybe a pic of one on a Lotus showroom floor?
