The only guy in wellington to use is Roy McGuinness from McGuinness Classics.
really nice guy, a little eccentric flavour, drives a Rover, but really knows his classic british german and american stuff.
He is actually a RMVD as well, anyone can write a price and do a valuation, but only a RMVD is truely in touch with the market.
He valued my convertible about 6 weeks ago, very happy with the result. Let him know i sent you, he used to have his last lockup/workshop etc same complex as my work
