I was looking at a Prius and it said 2013 Toyota Prius Five and the pictures had these badges "XSP" on the trunk lid as well as on the headrests. It had the Plus Performance Package wheels but I did not see any special aero kit and looked stock height. When putting in the VIN at Toyota it came up as a Toyota Prius Two and I could not see any extra packages installed. So what is the Prius XSP, is it a dealer added package? What years did the Plus Performance Package come as an option on the Prius? On Toyota's VIN search what do I look for on PORT OR FACTORY INSTALLED EQUIPMENT to identify a Prius as having come with the Plus Performance Package? Can you order from the dealer or online all the pieces of the Plus Package?
Could be a GST add-on. There is no XSP package but there was a Performance Plus package that could be added to.... I think any? Prius trim level. It started in 2011 but I can't remember if it was offered all the way to the end (2015). Here's the original press release. 2011 Toyota Prius Offers All New PLUS Performance Package | Toyota USA Newsroom
Saw a "TSS" package recently. Had the black leather seats with blue stripes running down the middle and sides, not very attractive as well as some cool dash and door trim add ons (not sure what to call it). Otherwise it looked like a Three.
Those are PLUS wheels. Whatever it is, it's a 3rd party deal (either with the original dealership where it was first sold or some other vendor). The door panels are cloth while the seats are leather.
