Maybe I've missed the suggestion, or maybe it's already available with the S2 license, but a car much like the 1st generation Mazda Miata.. small, lightweight RWD roadster with, a small displacement, low output, smooth revving powerplant.

) Even if it had to run with only "Miata's", it'd have to be killer fun. I know it's a completely different game, but my favorite race on Granturismo 3 was the 2 hour enduro with stock Miata's. All you could change was tire compounds and which edition of the car you drove. I always ran the lowest HP edition and "crappier" tires, so I would run equal with the pack, and pitting had to be strategically timed. I want that, with all the nuances of LFS! Of course there could be a hotter, "Mazdaspeed" version that might be competitive with some other cars in the game, I'm not really sure there, I'm still S1 and a n00b.
