I just insured my mi16 205 declared for £100.50 yesterday .if you need any info pm me .When insuring the 205, I found most underwriters won't touch it due to the engine swap - Greenlight, then Adrian Flux are the only ones that will cover it.
Adds at least £200 every year over a classic policy just because of the engine - I would think about going back to a 1.9 8v and modifying instead just because of this.
