In 1990 Mr Watkins built the "Impressed" also
based on a Hillman Imp which stood at 26 in (66cm) and in
1999 he held the record with "Lowlife", built from a Mini,
which was 24in (61cm) tall.
"The original car [a Hillman Imp] has been
cut down by 30in in the body, the suspension has been lowered
by 9in and the roofs been removed so its left us with a total
height of 19in at the highest point," Mr Watkins said.
Batmobile had a jet engine so I thought 'great, lets
stick a jet engine in' and built a jet engine and put that
in the back as well.
"Cost I don't count because I get upset and depressed
if I count - it's the wrong side of £10,000 anyway."
