With plenty of options attached, our test car weighed in at 670kg, distributed in almost perfect proportion between its axles; and, on paper, that gives it a Porsche 911 GT3-bashing 376bhp per tonne, and enough torque to weight to shade a Lamborghini Aventador S.
When you’re paying for performance credentials like that – and particularly if you’re assembling your car yourself – you’re likely to overlook the Sport 250’s looks, which, it must be noted, aren’t its greatest asset.
That plastic bodywork makes for an uneven paint finish in places, as well as plenty of ugly panel gaps. The bulge in the car’s bonnet, meanwhile, and its high-set wing mirrors and high-rised roll bar cause it to be it notably ungainly and less visually appealing than a Caterham, even from a distance.
It’s a good job, then, that Sport 250 owners are likely to have formed a deeper and more meaningful bond with their cars than you might with so many modern sports cars. Building your own car means literally tailoring it to your own specification – and it’s a spec that you can have with uprated driveline, suspension, wheels, tyres, brakes, seats and interior entirely as you prefer.
Among our test car’s upgrades were Westfield’s limited-slip differential and wide-track wishbones; ‘track day’ adjustable shock absorbers; suspension anti-roll bars at the front and rear; ‘race’-level brake calipers; and 8.0in-wide lightweight wheels with Toyo Proxes track-day tyres.
