I have lots of suggestions and I didn't see any of these in the OP, so hopefully nobody has said them yet. Maybe some of this stuff is already in the game, I only played for about 5 hours last night and am still doing the amateur races. If any of this is in the game let me know, I'll be super happy
Most of my update suggestions have to do with how you search for and buy cars. I'm very picky about the cars I buy, I hate having tons of cars in my garage when I only use like 5 of them. Maybe I'm weird, but I only like buying cars I plan on using for a long time. Having like a hundred cars makes me feel like I should be using them all.
There are over 1000 cars in this game, and if you don't already know what you want to buy it's a huge pain to find and compare cars.
1.
The ability to tag cars for comparison. As you go through the dealerships you could press L1 or something to tag the car for comparison. When you have a bunch of them selected, you press a button that says "Comapre Cars" or something and it shows you a list of all the cars you tagged and their stats in a nice table. You can move around the table, sort by different things (Press the BHP title to sort the cars by BHP) and when you find the one you want, you can click the "Buy Car" button next to its name. I don't know very much about the differences between cars, and trying to remember more than just the difference between BHP and weight between several cars is a huge pain. I would love, love, love a way to be able to put two or more cars side by side, see what the differences are, and choose accordingly.
2.
The ability to search for cars in the dealership based on different parameters. Rather than look through every single dealer to find what you want, you could open the Search menu and enter what you want. So if you want to do the pre-1970's Japanese Classic car race, you could put in Year: Pre 1970 Country: Japan and get a list of all the cars that fit the description. You could toggle showing new cars, used cars, or both in the same list.
3.
For races with restrictions, a button which goes to the dealership showing you all the cars that satisfy the restrictions. Some races have like 20 cars that fit the description, and usually I don't know what any of them are. This would make finding the right car so much easier than writing down all the cars that fit and searching through the store to find the one you want. Especially if it showed all the cars that match in the comparison table like I suggested in my first point.
And some non-car-purchase ideas:
4. Being able to see the prize pool of a race before you start would be just dandy.
5.
A "Retry Race" button when you finish a race. As it is now you have to quit the race, get XP and money if you earned any, load the race up again (yay minute++ long loading screens), then click start. Since the track is already loaded being able to retry the race before it quits would save so much time.
6.
Offline leaderboards + multiple profiles. My housemates and I are setting up a leaderboard for our house. Right now we just have pieces of paper taped to my housemates door... an actual in-game, offline leaderboard would be awesome. Finish a time-trial and when it logs your lap time you should have the ability to specify your name rather than just use your PSN name so you can tell who did what lap.
7.
Four player splitscreen! I don't care if it runs at less than 60 FPS and the graphics get worse, I REALLY want to be able to play 4-player splitscreen!
8.
More classic American cars. There's a crappy Subaru 360, but no Chevy Malibu, no Pontiac Bonneville, Cadillac Fleetwood or Coupe de Ville. So many awesome old cars that aren't in the game that I'd love to drive.
also, first post on these forums!
