I built one of those about 25 or so years ago .......in black too, with a 2 litre tuned mk3 Cortina engine in the front. Thing was virtually undriveable...heavy steering.......virtually no rearward vision (unlike my Blitz).......got as hot as a greenhouse in the summer and stunk of glassfibre. In the end I got rid of it. Looked nice though!
Now I drive more practical cars. Generally.
