Very sorry if this isn't the correct spot for this as I didn't see any kind "edit" button on the page.
The level 4 body shows a .5 upgrade for 125gold when it should be .4 upgrade. Also -.01 acceleration, not -.02
Longer version is more of a rant. :-)
This Jaguar has 30% off upgrade sale for me right now and I have all 3's for a 90.5 PR. I was considering upgrading it to 93 just to complete the Elite series it is in (for 32 gold reward). I had calculated on it being .5 for 4343444 for 481 gold which is ridiculous. But with it .4, the cheapest I see is 4434444 at 607 gold and there's no way that's worth it.
