• Dealership Manager / Director, Croydon Wholesalers in Central Park Drive, Henderson.

• Supra.
• 1997 Toyota Aristo V300 Vertex 3.0 Twin-Turbo on Ray’s 18”s.
• 1973 Triumph TR6 Convertible, original NZ-RHD with 150bhp.
• 1961 Plymouth Fury 2-Door Hardtop 318 factory-optioned car

• Bought in August 2000 from auction in Japan. Owned ever since.

• It must have been a fairly quick car in Japan, although most of the mods appeared to have been removed prior to auction. When we bought it, it still had the Trust drag-spec FMIC, a Blitz ECU with aggressive ignition curve, big-bore exhaust (totally trashed!), damaged Rays Engineering 17” alloys, and boost gauges etc.

• Anything to do with cars, really- I like (and will own again!) classic American iron from 1958-1961, especially ’59 Chevs, ’58, ’60 and ’61 Plymouths, ’59 Caddies…
• Early Japanese performance cars- would like to own a mint RX3 Coupe, a 240 or 260Z, an early Skyline / 240K, or early Cosmo from the 60’s.
• Import drag racing, big-rig drag racing (in the States!), rally, JTCC, BTCC etc.
• Really interested in drift racing, maybe something to try next?
• Other than cars….
• Road culture- Route 66- have travelled Route 66 seven times since 1994.
• American pop culture.
• Heavy equipment (I used to be an industrial auctioneer with Turners)
• Stormchasing- annual expeditions to the Plains of the USA to chase supercell storms and (hopefully) tornados, plus baseball-size hail, extreme lightning, straight-line winds etc.
• Photography- keen amateur.
• Model-building- no, really!
