      Best Skyline ever

      No-one in Aus/NZ would pay that much, because they remember when a turbo Skyline/Silvia was a cheap but awesome alternative to the mediocre shit sold here locally at the time. I'm sure over in USA there are enough trust fund kids who will have their R34 GTR, whatever the cost

      Import insurance in 2025

      By Kinkstaah · Posted

      I am stuck with enthusiast and very unhappy, even though Lumley, Shannons and Famous are all options, they all require a lock up garage, and my situation (basically a walled off compound from the street) is insufficient because the car is under a carport. I'm confident to resolve the situation I need to build a roller door with fascia in-front of my roller gate which is a solid opaque metal rolling gate. In any other universe moving the roller door 2 meters in-front of the garage door would still constitute the same amount of security but oh no. My insurance rates suck to the point of when I joined a market research for Enthusiast they were all surprised that I paid about 2-3x what other people were paying with Enthusiast when I asked them why their rates were so high. If I lie about having a garage, I save like $10 a month with enthusiast. (It's about $2600 p.a for 5000km of driving for a very unsustainable agreed value). Lumley has terrible reviews but @Duncan made me consider calling them when renew time came up - but their horrible reviews plus Christmas time made me... forget.

      Not far. If all you want to do is know that they will reciprocate and move oil around a tiny bit, then a metre or so is all you need. Half metre fore and aft is enough.

      It's fine. Basically if it has seized (eg due to moisture/rust in the bores) it will either break free on the starter or it won't turn....then you'll know it is freed up If it turns and doesn't start (reasonably likely) you will need to troubleshoot but most likely issue is a seized injector from moisture; same if it starts but missfires. Anything else could have happened (eg mice nibbling electricals) but the only way to find out is to close your eyes and hit the key I'd also change the fuel filter again after a few minutes of running as it may catch a heap of crap on first start
