You’ve probably imagined crafting a car that matches your tastes, performance goals, and budget, and this article shows you practical options that make that possible. You’ll discover seven kit cars that let you take control of design, parts, and performance so you can build a custom ride that reflects your skills and preferences.
Expect a mix of classic replicas, lightweight track-focused machines, and modern supercar-inspired kits, with notes on drivetrains, build complexity, and the kind of experience each offers. This guide points you toward choices that fit a range of budgets and ambitions so you can figure out which project sparks your excitement.
Factory Five MK4 Roadster
You’ll recognize the MK4 Roadster for its classic 427 Cobra silhouette updated with modern components.
Factory Five sells it as a well-engineered kit so you can choose engines, transmissions, and suspension to match your goals.
Assembly gives you hands-on control over fit and finish, and many builders report strong on-road performance.
Prices for a complete chassis kit start around the low tens of thousands, with total build cost varying by donor parts and options.
DF Goblin Supercar Kit
You get a lightweight, exoskeleton kit that aims for supercar feel without the price.
The Goblin uses a custom tubular chassis and common donor parts (Chevrolet Cobalt in V1), so sourcing components stays practical.
Assembly suits home builders who like hands-on projects and track days.
You can choose different body options and upgraded suspension on newer versions to match street or race use.
Westfield SEiGHT
You’ll recognize the SEiGHT by its minimalist Lotus Seven–inspired body and throaty Rover V8 options that give it real punch on back roads.
Building one is hands-on fun; kits range from straightforward bolt-together projects to more involved builds depending on how original you want it.
The driving feel prioritizes raw engagement over comfort, so expect tight steering and a lively chassis.
If you want a classic British roadster experience without a huge price tag, the SEiGHT is a strong, characterful choice.
Caterham Seven 620R
You’ll feel how lightweight design sharpens every corner; the 620R pairs a supercharged 2.0L engine with an obsessive focus on power-to-weight.
Its cockpit is spartan but focused, putting you close to the road and rewards precise inputs.
You can use it on track or on spirited back roads, though it prioritizes raw performance over comfort.
If you want an uncompromising, driver-focused kit car, the 620R sits near the top of that list.
Locost 7 DIY Kit
You can build a lightweight, Lotus Seven–style roadster using Locost 7 plans and a donor car like a Mazda MX-5.
The project suits hands-on hobbyists who enjoy fabrication, wiring, and learning vehicle systems.
Costs vary widely based on parts you reuse or buy new, so set a realistic budget before you start.
Completed Sevenesque cars deliver nimble handling and strong value when you assemble them carefully.
Ultima GTR Kit Car
You can build an Ultima GTR as a kit or buy it factory-completed, depending on your skill and budget.
It uses robust American V8s and a simple, track-focused chassis that delivers very direct performance.
Assembly suits builders with basic automotive tools and patience; many first-time builders finish high-quality cars.
Expect a high-performance result — but plan for costs beyond the kit for engine, transmission, and finishing.
Porsche 356 Speedster Replica
You can get the classic 1950s Speedster look without the vintage price by choosing a 356 replica kit or turnkey build.
Many kits use VW-pan platforms or custom tube chassis and offer aluminum or vintage-style hinges for authentic fit and finish.
Builders range from DIY suppliers to companies that deliver finished, road-ready cars.
You’ll find options for customization, modern drivetrains, and varying levels of historical accuracy to match your budget and goals.
