November didn't have an Alfa
The Muscle Car Pack didn't, but there was a DLC Alfa available via pre-order bonus, which is now available to everyone, so...There technically was a DLC Alfa in November.
Most DLC Cars:
1. Ford - 7
2. Chevy - 5
3. Alfa Romeo - 5
4. Dodge - 5
5. Audi - 3
6. BMW - 3
7. Honda - 3
8. Maserati - 3
9. Pontiac - 3
There are a few with 2 and a bunch with 1. But...Including the Launch Bonus Pack, 70 cars have been added. Out of those 70, 37 have gone to one of these nine manufacturers. That's 53%. And if you add in the 6 from Koineggseg, Aston Martin and VW, who've each gotten two DLC cars, that makes 61% of all DLC cars have gone to manufacturers that have already received a DLC car.
As for my opinions:
1985 Mazda RX-7 GSL-SE - meh. Rotaries are kinda cool, but I think I've gotten enough of them from Gran Turismo.
1972 Mercedes-Benz 300 SEL 6.3 - I've seen this car a lot around town, so it'll be a fun car to put stickers on and do lemon races with.
1959 Cadillac Eldorado Biarritz Convertible - A caddy that's not a CTS-V is always welcome. I got irritated in FM3 when, by the end, there were 4 or 5 CTS-V's including the race cars, which is boring. So, an old classic Caddy is a sight for sore eyes.
1997 Volvo 850 R - T10 is finally putting wagons into these games. And finally one that'll actually be competitive without an engine swap. The 850 R is a Touring Car Champ and I expect to see a lot of replica paint schemes with this one.
2011 Aston Martin #009 Aston Martin Racing AMR One - Aston's new LMP1 car. Should be fun to paint.
2011 Mercedes-Benz #35 Black Falcon SLS AMG GT3 - Another fun one to paint, and all we need is the McLaren MP4-12C GT3 and we have all the GT3 cars, I believe.
2011 Maserati Quattroporte Sport GT S - Maseratis are always fun.
2012 Jaguar XKR-S - Jags are always fun, too.
1995 BMW M5 - Meh. I'm not a big BMW fan.
2012 Scion tC - Well, I suspect we can blame this one on Tanner Foust. So, make this thing into a drifter, 'cause it's all it's good for.
