New SVX OWNER: how's maintenance?

Hi, i juss bought a 92 SVX with about 229,000 kms already on it. It's in great condition but i know that the wheels or something around there can't really handle the weight...anyone know what I am talkin about?

Also, how is maintenance on this car? like is it cheap, reasonable or do i have to start counting my pennies?

any help would be appreciated..
