This particular model is one of the earliest to come from Westfield founder Chris Smith. It was purchased and partially assembled in 1982, but never fully completed. The seller makes a "honey-do" list needed to get this thing on the road:
Install fuel cell
Install radiator - provided
Install windshield - provided
Door locks - barrel locks really
Call your insurance agent
Of course there is more
Turn key and your [sic] the man
You'll also need working lights, driving goggles, and a moustache. Maybe an umbrella too.
Which brings us to its daily drivability. Full elemental exposure is a concern for the hides and gizmos in any modern luxury car, not a bare-bones racing toy. If its harsh ride is a problem, you're probably the guy who complains about lack of WiFi connectivity at an Amish farm. As for track use, buy a Caterham instead. For a car with 1/3 the curb weight of a 2015 Mustang, these Westfields are still quite slow. Car & Driver clocked a 2007-built one at 9.3 seconds to 60 mph, with the 74-horsepower MG engine. But remember this: This Westfield went for sale about the time Lotus announced an optional automatic transmission in the Exige. Maybe you should impulsively buy this anyway, just to offset the bad automotive juju.
PhiLOL actually likes the tuna here, but abhors structural rust. Save the manuals.
