I just bought a 06 Nismo with 87,XXX miles. I was wondering how many miles I could expect if I took care of it and had it serviced regularily? Also, is your high mileage on the original engine/trans/rear or rebuild on any of the 3? I know it's a guestimate but if any high milers out there can advise their mileage and other, this may give me an average I may can expect from mine. Was hoping to get at least 10 years/100,000 miles out of it.
