Anon from
>>7808150 here. I went ahead and ordered the stuff from Cracklink that I was fretting over hours ago... The good news is that I was able to reduce the price of the list of parts I had in mind by almost half due to looking around and finding a store that had cheaper prices and a better approval rating overall. (Also, who knew that sometimes it's easier & cheaper to just buy 8 separate wheels and 8 separate tires that go with them instead of them assembled already?)
Of course, I went ahead and started adding more stuff that I wanted along with the two little cars, so I ended up spending the same as before. (Pic Related is the car design, except the windshield/screen is Trans Bright Orange now because that piece in Trans Black is rare and the stores on Bricklink that have it know that and price it accordingly.)
