Bit the bullet and bought a hardtop £300 and it was local, off an 03 MK2.5 Mx 5, fits fine with adjustment but heated screen does not plug straight in found a solution but was expensive after research my car a 93 Mk 1 Eunos has the wiring in place bought a relay for £6.50 (plugs in near battery in boot fuses in place as it had an electric areal) dash switch £40 (ouch!) but will plug straight in just need to rewire the top to the car as plugs are different.

These guys supplied my wheel adapters 20% discount at the moment.

OP - What's the latest on the DVLA issue?

DVLA I will need to get back to them.

In the mean time changed the Nardi wheel centre for one from these guys www.bellavolante.co.uk fitted with a bit of fettling also Toyota key of ebay cut to fit for £2 he had to cut it backwards as its slightly shorter than the Mazda blank, works fine though.
