History

The car was SVA’d when build was completed in 2001, and registered on a 1975 age related plate as a consequence of having demonstrable provenance to a donor Ford Escort.

The car remains road registered and can be tax’d and MOT’d.

Tax is free due to historic status.

The car was converted to a 200bhp Rover K series in 2004 before competing.

The car was then converted to a 306bhp Duratec in 2018.

It has done somewhere around 4,000 miles in total.

The car has been sprinted and hill climbed and is believed fully legal for RAC MSA approved circuit racing and speed events in UK.

 

The car is currently sorn with no MOT but can easily be MOT'd if the buy wants as all the lights etc are present and working. 

 

Offers around £20k
