Extended maintenance worth it?
I know extended warranties have been extensively discussed, but I am wondering if extended maintenance is worth it on an E90 M3 6MT. It is very expensive - about $3300. I can see using it for: 1 brake service (both axles), 74K mile spark plug change, 1 brake fluid change, possibly a clutch disk replacement and about 3 oil changes. Any thoughts? Thank you in advance.
