Agreed with Bubba, must have deep pockets if your planning onto buying these cars as if something small breaks, its a big pay out, service is alright as its about 1k a year or whenever it shows on the dash.
Looking at a Japanese car, you'd be getting that service about once every 3months? or less depending how much you drive so thats like $200 x 4 services a year = $800 a year..so not really much different for service.
Just parts are hefty. example:
when I had the Alfa Romeo, costed me 3k for a stock clutch, while with a the skyline it woulda costed me just under 1k for a upgraded heavy duty clutch
Good luck with the purchase anyway.
