All of them.
One wouldn't think that designing what is basically a catalogue website would be that difficult. One would be wrong. Fiatsler is a PITA. BMW is better than it was but still could use some updates. VAG isn't too bad for the most part. Ford and GM are kinda meh, but I could configure stuff well enough. Toyota and Honda likewise.
Nothing is really grabbing my attention. The pony cars add up pretty quickly. They aren't out of the question though. Not interested in SUV/CUV's really.
Not much at GM or Ford aside from maybe the Regal Sportback, the Focus ST and of course the Mustang and Camaro. Honda Accord 2.0 is still on the list, really don't care for the looks of the Civic. Nothing at Fiatsler. Nothing at Nissan. Not really into Mazda aside from the MX-5.
VW has the GTI, of course and I could do with another Passat. The Passat GT trim looks pretty good and the 3.6 hauls. I'll be interested in the GLI when it appears. Audi doesn't do an A3 with the stick, which is odd.
Toyota doesn't have much beyond the 86 that I really want. The Prius or it's derivatives would be great fuel savers, but I don't drive much, and I hate the looks inside and out. Lexus has something like $5k on the IS300. Inside is fine. Outside is butterface, but not a deal breaker.
Subaru has the WRX, but without the hatch it looks awkward. Not a deal breaker.
So I guess pony car, GTI, Focus ST, WRX, Regal, Passat, Accord, Lexus IS 300. Longshot would be 86/BRZ, maybe Prius.
Nothing if not eclectic.
