i'm driving a '97 VQ25DE A32
did some minor mods such as K&N drop in, decat, minor bits of air magic, chassis strengthening, upgraded tyres and a few more. never experienced ECU problems as mentioned by some posters above. FYI, i also own N16
problems faced so far: are typical wear and tear items, belts, rotor, pads, suspension, bushes, hardened rubber hoses... you get the drill...
FC wise, my worst was 19km/lit. (eerr.. don't ask why, but it was a very fun drive, and everything else is quite blur)... my best is around 10km/lit, drive about 50/50 city/highway.
fits 4 big sized adults comfortably and 5 normal adults comfortably. power wise 2.5 is the most balanced with road tax if you're picky about it. otherwise, just go for 3.0.
a lot of minor mods can be done to further transform the car into a comfort and much better cruiser.
only think i don't like is the turning radius and the length! harder to park in some kl car parks!
maintenance wise, cheaper than toyota camry (a family member used to drive ACV30 before upgrading to ACV40), not too sure about perdana though...come to think of it, i spent more on enhancing the ride than i repair /maintain it...hhhmm....
you can also get new parts from big distributors such as vanli (they'll order from japan if you don't mind the price), recon parts are also common for the steering rack and compressor...
chop shop wise, no issue at all, since the halfcut of VQ25DE is getting very popular with Naza Ria owners...

only thing is to spend a bit of time shop around and bargain for the best price...also upgraded some of my electronics from chop shop purchases...
not to worry on the parts most of the 2.0 to 3.0 family can be used with each other (and across models too!) like A32 shares the same part number for the air filter with N16...
it's a good buy when you find one in a good condition, but then again, your luck may vary.....
good luck bro in your quest!
if you are interested, my mechanic's friend is selling his 2.0 year 2000 after upgrading. you can PM me for his contact if you're interested...
