Looking for a Set 42143 Alternative? An Honest 1:8 Guide (2026)

BUYER'S GUIDE · WRITTEN BY A BRAND THAT SELLS A 1:8 CAR

Set 42143, the LEGO Technic Ferrari Daytona SP3, was for four years one of the easiest answers to "which big brick supercar should I build?". It has now left retail, which leaves a lot of builders searching for an alternative. This guide lays out the realistic options: buying a 42143 anyway, picking one of the brand's current 1:8 cars, or choosing a 1:8 kit that actually drives. We sell one of the cars discussed here, so weigh our view accordingly. Every figure about other makers' sets was checked against Brickset, Brickfact, Merlin's Bricks or published reviews in November 2026, and anything we could not confirm was left out.

What set 42143 is, and why people now look elsewhere

The Daytona SP3 set has 3,778 pieces and builds a 1:8 model about 59 cm long, 25 cm wide and 14 cm high. It launched in June 2022 at $399.99 and later in 2022 moved to $449.99, the US price Brickset records as its last retail price. Underneath the red bodywork sit an 8-speed gearbox, shifted with paddles either side of the steering wheel plus a forward, neutral and reverse selector in the centre console, a V12 with moving pistons, working steering and butterfly doors.

Brickset's review called it "the ultimate Technic set" and also listed honest drawbacks: instructions that could be clearer in places, wing mirrors that flap about, and a gearbox whose effect on the rolling model is minimal. Its later addendum noted two instruction errors, one in the gearbox sequence and one involving two missing black panels. None of that stopped the set from becoming a favourite. What changed is availability: Brickset lists its retail run as 1 June 2022 to 31 July 2026, and Brickfact also marks it retired in July 2026.

So the people searching for an alternative today usually fall into one of three groups. Some still want this exact car and are wondering whether the secondary market is worth it. Some want a 1:8 supercar of the same calibre and do not mind which one. And some liked the idea of the set but always wished it could do more than roll when pushed, because like the brand's current 1:8 cars it has no motors.

Five 1:8 options side by side

Path 1: buy a 42143 anyway

If the car itself is the point, this is the right path, and we would rather say so than talk you out of it. It is the real car's official model, it carries the maker's name and badges, and no alternative from anyone, us included, will scratch that particular itch.

Just go in with realistic numbers. Brickfact's price tracker, checked in November 2026, showed an average secondary-market sale of about $386, while the cheapest new copy it tracked from a large retailer was $629.99. In practice that means two very different markets: opened or used copies, and sealed boxes priced as collectibles. Before you pay for either, a few checks save a lot of grief:

• ✓For a used set, ask whether it is complete, whether the stickers are already applied, and whether the numbered bags and the instruction books are included. A 3,778-piece set that is missing a handful of gearbox parts is a frustrating project, not a bargain.
• ✓For a sealed set, ask for photos of all box seals and compare the price against recent sold listings, not asking prices. A box is only worth what someone recently paid for one.
• ✓For missing parts, BrickLink, the parts marketplace the LEGO Group bought in 2019, is where most builders source individual pieces for a retired set.
• ✓For the build itself, read the gearbox section of the instructions twice. Brickset flagged an error in the gearbox sequence, and a gearbox mistake found three bags later means taking apart the chassis.

Path 2: a current 1:8 car from the same line

If you want the same kind of experience, a big hand-operated mechanical model with an official badge, the brand still sells two 1:8 cars at the same $449.99 price point.

42172 McLaren P1, 3,893 pieces. Released in August 2024, 59 cm long, with a 7-speed gearbox, a V8 with moving pistons, butterfly doors and an adjustable rear wing. Brickset still shows no exit date for it. It is the closest thing to a like-for-like replacement for 42143 in size, price and build style. We compared it with 1:8 alternatives in detail in our set 42172 comparison.

42232 Koenigsegg Sadair's Spear, 4,104 pieces. The newest entry, released in July 2026 and the largest of the line by piece count. It is 59 cm long with a 9-speed gearbox shifted by paddles and a rear clamshell that opens the doors and bonnet in one movement. Our 1:8 buyer's guide covers it alongside other 1:8 kits.

The trade-off is the same as with 42143: these are mechanical sculptures you operate by hand. Neither car has motors, and the gearboxes are something you shift and watch rather than something that changes how the car moves.

Path 3: a 1:8 car that drives

This is the path for builders whose real wish was "I want it to move." Several makers sell 1:8 kits with motors, a battery box and a handset in the box. Two examples at very different prices:

CaDA C61042W, 3,187 pieces. A 52 cm Italian-style supercar designed by Bruno Jenson, listed by Merlin's Bricks at $259.99. The remote handles forward and reverse, steering, a multi-speed control and the front and rear LED lights, and the car has independent suspension with shock absorbers. It is shorter than the 59 cm sets above, which matters if you want a matched row on one shelf. We cover the brand in more depth in CaDA vs Mould King.

NexusBrick Zenith 720S, 3,658 pieces, $299. Our own 1:8 supercar, 58 × 30 × 15 cm finished, so it lines up with the 59 cm cars on a shelf. It is the one we know best, so it gets its own section below.

For the wider category, including what "remote control" actually covers on different listings, see our guide to brick RC car kits for adults.

Where the Zenith 720S fits, and where it does not

Here is what the Zenith does, stated plainly. It drives and steers by remote. The scissor doors, the opening roof and the rear wing lift are motorized, the suspension height is adjustable electrically, and the LED headlights work. The box contains six motors, two remotes (one for driving and steering, one for the body functions) and two rechargeable battery packs.

And here is what it does not do, because buyers coming from 42143 will ask. It has no multi-speed gearbox to shift, and we do not claim an engine with moving pistons for it. If watching a hand-turned V12 and sequential gearbox work is the part of 42143 you loved, one of the hand-operated sets in Path 2 is the better choice. The Zenith is for the builder who wants a big model that does something when it is finished.

Three more honest differences from the official 1:8 cars:

• ✓It is an original interpretation, not an official model. There is no car maker's badge on it. If the badge matters to you, it matters, and Path 1 or 2 is the answer.
• ✓The instructions are a compact printed booklet. Some of our reviewers found it hard to read, so ask any seller, us included, whether a digital version is available before you buy.
• ✓The decoration is stickers, not printed parts. We wrote a full guide to applying them well.

On price, the arithmetic is simple. At $449.99, set 42143 worked out to about 11.9 cents per piece, 42172 to about 11.6 and 42232 to about 11.0. The Zenith at $299 is about 8.2 cents per piece with the motors and remotes included, and the CaDA C61042W at its $259.99 list price is about 8.2 cents as well. Price per piece is not the whole story, but it does show that a motorized 1:8 car does not have to cost more than a hand-operated one.

Frequently asked questions

Is set 42143 discontinued?
Yes. Brickset records its retail run as 1 June 2022 to 31 July 2026, and Brickfact lists it as retired in July 2026. You can still find copies from resellers and on the secondary market.

Can I add motors to 42143?
The set has no motors, and motorizing it means buying a separate motor kit and modifying the model. Third-party kits exist for it, but that is a project in its own right, and the result depends heavily on the kit. If driving is what you want, a kit designed with motors from the start is the simpler route.

Will a Zenith 720S sit well next to a 42143 or 42172 on a shelf?
In length, yes: 58 cm against 59 cm. It is wider at 30 cm, so allow a shelf at least 35 cm deep, plus room if you want to display it with the doors up.

Does the Zenith 720S have a gearbox like 42143?
No. It has no multi-speed gearbox to shift. Its working functions are remote drive and steering, motorized doors, roof and rear wing, adjustable suspension and LED headlights.
