Why the McLaren Senna is just 151 rp in event

Same here, just got an update and the car needs 707 car power (german version, dont know english terms) and it has 151 and upgrade blue prints I have -1 from -1 possible -.- I can drive 99km/h with that McLaren Senna, it starts with 100... time runs out when I'm just at close to ~40% driving more or less perfect (not hard to make no crash with 99km/h...), pls fix this... I had no events for over 1 week or so, and now its such a crap :/ just made chapter 12 and now I'm like: wtf? which car to continue with? anyone idea? I do NOT spend any real money for THIS! Is it worth to continue?! until now I drive a Subaru Impreza WXI or how its called703 ,max with blue prints and normal parts).

I try to get the Toyota Supra to the next star, but I guess it will be in the same class, just finished chapter 12 and got the Mustang GT and Porsche 991 now... bot both suck yet, I try to collect the needed parts (one needs 5x each, the other 3x...) but for the porsche there is no way to get blue prints like for the supra... the viper GTS I started to buy blue prints for money recently (all kinds of blue prints), but god knows when I will have enough to build it, it looks like the only car which can top 703 right from the start and is available without tons of gold?! I didn't know it, I had sometimes the chance to buy the prints, but didn't had so much money and thought its waste...

is it worth to continue or will it be very hard?! When I reach level 50 for chapter 13... now with level 45 I will have the viper until than if I don't stop, but I really lost motivation with the 2 new cars being good but hard to get blue prints, I also try to build the falcon from mary chapter 11 boss, got almost the half to build it.... I can only drive the final mission of chapter 12 until level 50, but its the first time its yellow and 1 mistake and I lost the game in the mission for Mustang GT blue prints and the 1:3 chance in reality for me is more like 1:6, last 9 supra races brought 1 blue prints, last 12 at least 3...

losing against chapter 12 boss for the mustang blue print sucks as you can only drive max 5 races and than you leave, so losing 20% of your gasoline really sucks....I had a motivation to get a car better than 703 Subaru... but it looks quite bad I think as I see them now and the bug sucks too, and I even had such pink muscle car tires for the Mustang GT with 360 value I got them once in these golden chests...but drive this difficult races to get 15 blueprints or how much it needs to maybe get close to 700 with the mustang?! get supra to 5 stars and make the 4-star equipments in that "factory" ?! I think if its below 725 its no real motivation except maybe waiting for the Viper, but it can take weeks as only 5 are available each time for ingame cash....

i also got same problem and added the video on youtube of it recently, for solutions...

How far are you in the campaign and what car did you use for chapter 10 to 15 if you remember? Maybe also how "strong" your car was?! Because it feels really like 703 isn't enough for chapter 13 except you want it hard and every repeat will be a hard one (like the special events, but there its hard because you must play like crazy and even if you win every event once daily is not enough and you have to wait almost 5 hours until your tickets are full again...but if you win you get a badass highend car for free and not a "1:3" chance which for me is 1:6 in reality :X 

I guess only few win these event...The best I got is Day 5 first mission in the last minutes of the time, means 3 full days missing and I used on some days up to 15 tickets :D
