Some weeks ago I started a fresh EL career, with the purpose to use some cars that in previous games I hadn't tried, mostly classics. Sticking to the rule of leaving a car just after I got it to level 10, I added another rule: to keep switching nationalities, forcing myself to use italian, british, swedish, french, japanese, american, etc. So, I drove lots of fun vintage cars, like the Merc 300 SL, Lancia Stratos, Fiat 131 Abarth, Nissan 240, Citroen DS, the 60's Mini ... and when I finished with those, I moved to nowadays cars, always trying to use cars I had never used before. I was never in position to enter the Koty race (at least with a chance to actually fight for the victory) for the first 3 years of game, but, by the 4th, I arrived at the end of the year with a Mustang (it was the time to pick an american car) ... and I got second. Year 5 ended with an FF italian car (the litle Alfa, don't remember the number), and I tried the KotY again ... got second again. The end of year 6 found me with a Nissan 350 Z, and I got the win. In the meantime, I had made so many races that I had some 180 cars unlocked in EL, missing (apart from some other cars that rarely appear in a race) only the "R" cars. From this class I had unlocked only the BMW 3.0 CSL, the Toyota Supra JGTC and the Nissan Rally Raid car (I unlocked them in "one-make races"). So, I decided to start unlocking the other "R" cars. And here's where I found two things: a) the BMW is useless in a EL career, because all other "R" (circuit) cars are waaaay faster (accelerating, braking, cornering); I don't know if it can fight the BMW M1, because this one never appeared in a race so far; b) With he Nissan Rally Raid the game only allows two match races: Marco Strada wet and "Desert whatever"; and the opponent is always the Mitsubishi Rally Raid (I unlocked it); c) the only other "R" cars we can unlock in the roulette after a race (and I unlocked them using the Toyota) are the DTM Astra and Merc, the JGTC Nissan and NSX, and the Mclaren Race car; The other "Le Mans" cars (2 Audis, Mazda 787, Nissan 390 and Toyota GT-One) appear in the roulette, but the result is ALWAYS "no cars unlocked". Believe me, I tried to unlock them over and over again. So, by now, I switched my EL rules and I keep a close eye on the RS races calendar, just to have the right car at the right moment. The 12 months of this calendar alternate between "any car" months and "specific cars" months (FF only, RWD only, 4WD only, Rally cars only, Race cars only). And, in the "specific cars races" you always have a "R" car to unlock if you end the race in 4th, or better.* I have won a rally car in the "FF" week, but I didn't have the time to use it and check what other "R" cars I can unlock with it. bottom line: a) It seems that the game wants us to get a "litle crown" in every RS race to allows us to unlock all 211 cars in a EL career; b) It's a pitty the game doesn't give us at least one other "old" race car, just to be able to fight it with the BMW CSL (like we can with both the Rally Raid cars); but I'll reserve my judgement on this until I get the M1, probably waiting to be unlocked after a RS race somewhere in the calendar; * If I recall correctly, there are only two consecutive months for "any car (except "R") races", which are November and December.
