## Customer Reviews

### ⭐⭐⭐⭐⭐ great car once finished
*by A***A on 7 January 2026*

great for lego and car fans! easy to build and great present

### ⭐⭐⭐⭐⭐ Tricky for age group but looks great made up
*by S***E on 12 August 2025*

Great car, definitely needs to be 10+ lots of small fidley bits that need small fingers. Some adult help need for instructions but looks amazing when complete.

### ⭐⭐⭐⭐⭐ Complex enough to be a challenge, but a sensible time to build
*by J***S on 22 August 2021*

I'd say this kit hits the sweet spot of a decent price, a complex enough kit to be interesting and a sensible amount of time to build. The beautiful technic car kits at north of £100-200 are magnificent pieces of work, but they are also a significant financial and time commitment. This one is a generation ahead of the £18 Speed Champions kits, but only costs twice as much, so you get much more for your money. There are some nice touches like steering and an animated V8 engine, but it doesn't extend to proper gearbox, differential and suspension like the top kits do. That said it's a great medium level kit and very good looking when complete and looks something roughly like 1/12 scale, so it doesn't take up as much shelf space as the really big car kits.
