Flick switches, gauges, gear shifter trim ring and warning lights are all readily available.
The steering wheel looks like it's from Moto-lita.
The steering column shroud looks like a European Ford based on the hazard light switch.
The sat nav screen looks pretty generic aftermarket.
The 3 knobs above it look like simple custom jobs, as do the indicator stalks etc.
The small screen behind the steering wheel looks like an oversize Casio watch. But is probable part of an aftermarket traction control kit.
The heated seat switches may have come from a production car.
