Alright, so I got a couple notes here.
First, now that we can sell cars, and since the resale value is usually about half the original value, I'm thinkin' of just doing what a lot of people did for the "Firm Favorite" trophy, and buy ten of the GT Kart 125 Shifter. That way, I think I'll lose the least amount of credits, as opposed to buying a relatively costlier vehicle that many times.
Secondly, I've realized that I sort of prefer not to add a livery to some cars, as I feel that somehow, they look better in my eyes when they just have various custom parts installed, such as front splitters and hood pins. It's not like in GTS where we always had those number stickers plastered on, either. Heck, I don't even know if I wanna always equip custom wheels, either, since we can still widen the track even with the stock wheels. (Of course, that's if a widebody is installed to begin with.) Some of the factory wheels just seem to suit the car so well, that I can't seem to find a wheel design that could take its place, like the Porsche Taycan or the Pontiac Trans-Am. Overall, I get this gut feeling that these cars that use their factory colors/decals are more photogenic, and could make for better subjects in Scapes than my cars with custom liveries.
I'm also a bit annoyed that we still can't buy Guards Red as a custom paint, even after this most recent upate. Not that I was really gonna use it, but it seems like such an iconic color for Porsche. Ah, oh well.
EDIT: I also redeemed my engine ticket from the Mid-Engined Porsche menu today, as well as the parts ticket from the Renault menu. I got the engine from the GT-R GT500 '08, which is nice, and for parts, I got a Stage 5 Weight Reduction for the Ferrari Enzo! Yeah! Now if only I could get a Ferrari invite - though I may want it later than sooner, so that I can get enough credits for all three invite-only Ferrari models...
