Racing seats, lifter for peace of mind, LED wheel with or without carbon fiber trim(not a carbon fan here unless the interior is black, red, blue, yellow or grey), and sensors.
There's dozens of threads answering your question. Are you talking about must-have for ease of driving or for resale as these are two different categories? My 4 must-have options are sports rims, shields, painted calipers and LED steering wheel (I wrapped mine in leather as my interior is carbon fiber free). Useful options on my Spider are front and rear parking sensors and Homelink.
tried all three seat Options and went for the Daytona full electric, unless you are doing a lot of track work. rear camera, cruise control to keep your license
shields, LEDS on steering wheel, front rear sensors, upgraded wheels, suspension lifter only if the area you live in necessitates it.
By far the LED steering wheel. I won't consider a car unless it has one. Also I prefer the car has shields. Parking sensors would be nice along with a back up camera.
i have a steep drive and do not feel the lifter is a necessity. and i have never scraped the "nose". options i think are important: shields, homelink, rear camera, parking sensors, and most important of all, racing seats. as stated above, the more carbon the better, but aftermarket carbon can easily added for a modest cost.
LED steering wheel Diamond polished wheels Black upper dash Shields Electric seats w memory, elec auto dimming mirrors, Homelink Back up camera Mich pilot SS tires Black sports exhaust (no maintenance) Black headliner (no maintenance) Clear bra cowl forward plus running boards Things you might want to consider: Contrast stitching on dash and seats etc Cvallinos Front rear parking sensors if you parallel park (I don't) Lifter if you need it (I dont) You probably need an iPod connection for resale (I don't) Best
Shields the real must have. I don't care for them but they are a deal breaker for most everyone 20 inch wheels are the next must have. Same thing, cars without them are hard to sell Everything else is personal preference.
Remember you are buying a used car and prices are going to head down for at least the next 5-10 years if not more. So pay as little as possible for the best car. What do I mean by best, most recent production year, single owner, well maintained and serviced by a dealer you trust. Everything else is secondary.
front lifter system if you plan on driving your car in a city a lot and want to do so without anxiety i wouldn't listen to people saying it isn't necessary, they probably drive it sparingly and only on known routes in which case no you wouldn't need lifter. road trip to someplace new? you'll want that lifter for peace of mind, even if you never have to use it.
As for seats, you'll need to try them. Some here recommend the electric seats and Daytonas. I for one find the Daytonas pretty uncomfortable and "odd". Many here seem to swear by the carbon race seats for comfort, but to each his or her own. The size medium seats sure works well for my back and butt.
I drive in LA. Don't need the lifter. Also don't need camera either. I have sensors and have done 30k miles and haven't backed into anything. I prefer the standard seat with seat heaters, esp nice if you are getting the spider. I don't have the nav. Didn't like the plastics bubble cover and the additional hole drilled in the rear body panel. My google maps which plays on my audio system is so much faster to use and works very well. Must have: IMO the folding hard top. That's worth more than the carbon fiber, shields , led steering lights back up camera etc etc etc.
+458. Spider is worth every penny if living in warm climates. The capability to drop the rear window and listen to the glorious engine in Race mode is a very useful feature during my daily commute when the morning sun is too hot for top down driving. I like my standard seats. Had Daytonas in the California and didn't care for the lumps and bumps. Used Nav 3 times total in my California. Unnecessary for me and when in doubt Waze FTW. Honestly, I don't even need the front sensors. They make an annoying alarm when I come to a stop sign or intersection. I know this can be disabled but then I feel it defeats the purpose of having the front sensors on when I am not expecting a front end love tap. With the cab forward positioning of the 458, front visibility is great. Front and rear sensors are useful in my BMW 5-series as it's 192" length compared to 178" for the 458. Rear sensors are very useful as the buttresses obstruct some rearward visibility. If I order a 488 Spider I will go rear sensors only.
My front sensors only come on after reverse. If you don't use reverse the front sensors stop working until reverse is used again. It would drive me nuts if they were on all the time. Audi RS5 same way. Try pushing the button by the middle rear view mirror and see if yours will work like my 2012 spider. Best
The problem is when i need the front sensors i am pulling straight in and not reversing i.e. at physicians parking garage stalls with concrete wall front barrier and my cozy garage guarded by wife's shoe rack with a plethora of Ferragamos and the water heater. Front sensor helps prevent me from running into wife's shoe rack which is a couple feet off the ground. The water heater is big enough to avoid.
