basically you've got it sorted.
keep it oil'd regulary, keep things that wear out well and truley nailed.
and drive it nicely, and there is no reason it just won't keep on going.
there are always wear parts (without them, the whole car would have to be replaced), and the service book isn't always correct about when to replace them.
I personally deal with everything myself, as I know from painful experiance that mainline dealers just don't do it!
the biggest one they always 'avoid' doing is the anti corrosion warrenty (not a deal with >93 fiats, as it shouldn't rust unless its been badly repaired, or sprayed with chippings!), and rad flushs etc, oh and brake fluid, my personal fav, something that is elemental in the safe stopping of a car, so they miss it out, fantastic confidence insprinng stuff, done by:-
AUDI
BMW
FIAT
CItrofrown
renault (couldn't even figure out what day of the week it was, chuffing hopeless tosspots)
Saab (killed a beautiful rare car with their incompetance)
Volvo (three times fixed a high pressure fuel line (7bar) with what was basically washer hose, and sent it on its way, total reckless prats
)
Basically as you can maybe tell, I've lost all confidence in dealers, and their wheeling's, they sell crp cars for stupid prices and do nothing but lie and decieve.
The only garage that was actually to book, was the subaru garage in carlisle (now part of mazda or something), who actually did, and actually will, unlike most other garages about......
