Ok a few points from a JDM owner.
1. My transmission failed in 2 months after owning brand new JDM clutch seal popped at 6000 km's taking off agressively but not using launch cost $10-12 to repair.
2. If you live near Willall Racing great for servicing but otherwise its not good for servicing as nobody has a Consult 3 and if something electronic goes badly wrong in the car your kinda farked till you find someone with a consult 3 and you can buy them I think now for $10-15k yourself if you find someone who can get them. There are people who have them but they are very rare & you have to pay to use them if you can find them.
3. Yes we do get raped in Australia on cars & taxes not much you can do, just buy the car through your business claim $6000 in GST if you can and whatever other benifits that come with that, insurance & petrol it all helps.
4. Compare the R35 to a BMW M3, it eats it for breakfast in superior everything except ride comfort. Unique looks, speed, acceleration & gadgets etc. Not many other cars of the same price range to compare the R35 too as its too fast to compare much else.
5. If you buy a JDM you will NEVER use Launch control as you have no warrenty and these R35 transmissions fail a fair bit. Plus i've talked to a race team that used launch on their car quite a bit and blew first gear, then got transmission repaired again before blowing it again on race use. They do break the reports I believe are not over reported I believe they are under reported. Martin @ Willall Racing would know best I guess he repairs them all.
If you buy a ADM you can use launch control the cut down v2.0 which is extremely close to v1.0 in speed but without voiding your warrenty. But the car just jams 3.8-4.0 sec 1-100 just jabbing on the throttle anyways so launch is overrated and not really nessesary.
6. If you can get a JDM for $120,000 go for it, but I have a feeling there are more costs in there, rego is certainly $5500-7000 more thats for sure, thats $50,000 in money saved for warrenties people say are worth fark all when you try to claim something and you put that money aside to pay for repairs if needed. Your car might be off the road a bit more when something breaks but to keep your ADM warrenty I hear they make you pay $10k for new brakes & other stuff or you void the warrenty. Check into that stuff further though so much floats around the boards.
7. Have a good look at all the car colours, and make sure you test drive a R35 so you know what your getting into. Oh and when you get the car, get the blackest darkest tints you can. makes all the difference.
