- Car has been in the build since sourcing it from Japan in 2000. Originally I used it as a daily driver, although it is still fully street-legal I tend to only drive it now during the weekend or to race events. It is not a trailer-queen! I drive down to the NSDW events at Champion, put my drag tyres on, go racing, pull the tyres off, and drive back home again.

THIS CAR’S HISTORY:
- 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!
