I ordered a new Performante Coupe last November, with a planned April build.
Just yesterday, I even changed my order (not even sure if this is going to work out for me, also a 2000 EUR fee comes in effect if they can change it).
I studied the various options pretty well and I think I know quite a deal about them now.

Let me explain the options to you:

1. Bucket seats vs. Comfort Seats: For weekend fun driving, especially alone, the bucket seats are just fine and very sporty, maybe a bit uncomfortable but not as bad as many say. If you plan to do longer drivers and/or want to take your wife/girl friend with you, I'd choose the comfort seats. Passengers will complain about the bucket seats. If you are worried that the comfort seats do not offer enough side hold: They do, no worries. Unless you plan to track the car often.

2. Sensonum: Do you really think you are going to have the chance to listen to music while you drive? Or let me put it this way: If you drive mostly in Corsa mode, forget about Sensonum. Doesn't make any sense. If you drive more often in Strada mode, maybe. It isn't as good as the B&O system in the new R8 anyway (I currently have the R8 V10 Plus with the B&O system), this needs to be clear.

3. Style Package: If you choose to have (shiny) black wheels with your car, the Style Package is actually a must. Otherwise you get a dark grey matte plastic look instead. Works well (without Style Package) with silver and dark grey colors, also matte colors but not bright or very light colors.

4. Rear view camera and parking sensors (this could be standard in the US/Canada, I don't know): A must have option for the Performante because while visibility is quite good (you cannot really see the front hood or front side fenders though), it helps with certain parking/maneuvering situations.

5. Central lock rims (Loge rims): They look nice and I chose them for my car but be aware that by choosing them, your options for different rims (if you want some) and/or winter wheels (different rims with winter tires) will be very limited and it could get pretty expensive as well. Advantage: Stealing your rims wouldn't be that easy.

6. Tires: Be careful, the Performante is tire sensitive. Stick to the OEM Pirelli PZero Corsa. Some owners love to switch to different tires and often claim they are better, they're not! If you want to track race your car often, get the Trofeo R but to be honest, the Corsa is the safest tire for the Performante, especially in the wet.

7. Engine: Lamborghini apparently claims no run-in is necessary but if you want to have an engine with a proper power output and reliability, try to keep the engine under 4500 rpm and under 160 kph for the first 1500 km or so. Of course if you buy used, this is difficult to do and you never know what the owner did to the car.

8. There are various Ad Personam options available, including special colors. Matte colors need a special treatment, not always easy to keep clean if you don't want to hand wash the car all the time. Also, in case of an accident/repairs, special colors are more difficult to repair properly. Also more expensive to repair (if your insurance doesn't cover the cost).

9. Lamborghini Dynamic Steering: In my opinion, a must have option. It really enhances the driving experience because the ratio changes according to the driving mode and in Corsa, the steering is very direct. Not all drivers like it though, so you better take a test-drive.

10. Magneto-rheologic suspension: Also a must have, unless you drive on the track only. Bad roads make it necessary.

11. Lift: A must have option, do not buy a Performante without lift because you will damage the front spoiler at some point.

Have fun! If you have questions, just ask.
