You are right there is a heap of them out there prices vary and the 2009-2010 are sometimes cheap but other times people ask same as 2012 onwards prices, I'd only go for 2012 onwards, and plus side is you can buy decent ones from a dealer where as our JDM imports are very rare now so least buying a R35 would be easier and quicker then find that mint Skyline GTR needle in a hay stackI personally lusted for a 35, but I could not let the 32 go to pay for it, and I know I wouldn't get another as easily whereas if I was to sell the 35 there's a heap of them in varying price and performance and are more readily available. I feel that the 35 surpassed my expectations but the 32 started me on this merry dance as that set the standard for me in the 1st place.
As for the home Mechanic dealio.
Proud to say I've just done a 6 month oil and filters (airfilters oil and cabin filters) on my 35 after the last owners kept it up to date with Specialists every 6 months. I'm breaking the chain of its service history and I don't give 2 hoots 🥳
From a Resale perspective it may hurt it a little I'm sure IF (and that's a big if) I ever did decide to sell it but I have receipts for all the bits plus photos and videos of it being done but then selling it is not something I am thinking about.
Keep the 33 dude, value is only going up, 35's as nice as they are, far more of them about than 33's
That is exactly what I'd be doing you won't lose value on it doing things like this to them as that is "General Maintenance" jobs. and yeah totally agree that is a big IF as every car I have ever sold to a garage not one of them ever looked at the history I could make it all up and they'd believe it, a personal private buyer then someone may look but again it wouldn't make it lose value maybe they say I'll knock off couple hundred at that, even then you ain't going to lose the value of the car entirely
Yeah I do this to my R33 GTR always have, although I maybe do 1500-2000 Miles a year in it, and use it for only 6 months in a year so spring/summer time only and lock it away in the Barn for winter, after winter I change the oil/filter etc etc before Spring to use it again so safe to say the oil in my GTR is forever looking like newBTW, just to echo you, I also do oil every 3k, I did 3006 miles and wouldn't move it for 2 weeks till I serviced it 🤣
