to all future owners of 350Z: the other day i pumped full tank petrol cost me rm174.. and it can go for 500+km IF u drive constant speed.. i drove down to sg from kl and when i arrived at machap, i still have a lil less than half tank :)
as for the insurance, it really depends on how much u want to insured for.. for me, i insured it for rm240k which means about rm6,544 every year.. there goes about rm10k every year for insurance and roadtax.. u must be asking me why i insured it for rm240k.. it's becoz the Z is worth that much.. it's a 05' model..
btw, i just serviced my Z recently.. 2 days ago.. it was rm550 including labour charges.. rm495 for motul engine oil and oil filter is rm30.. as for brake pads, in april i change new ones.. rm820 for front and back endless pads.. so far i've not change the timing belt and i've been driving the z for almost 9 months.. it's my everyday car..
oh, i service the Z every 5,000 km :) hope all this info will answer some of your questions
ps: i bought the Z at beaucar.. and i know some skyline owners also bought their car with this car dealer.. if u want, i can recommend u to it :)
