I'm not aware of them needing regular valve adjustments, but then perhaps
the good people that service mine do it and don't say. Belts are every other
major service, though in theory with contemporary belt materials they should
last longer (I wouldn't take the risk). At around £1500 ($3000) for a
typical major service (the price list always says about half of that, but
'there's always something' with cars this old) they are among the lowest
cost Ferraris to own, but when parts are needed (unless you can get
re-furbished items) you are in for the same sort of costs as parts for a
430. Fortunately independent garages, owner's clubs and others can take keep
the costs down.

A couple of the more technically capable people in this group service their
own 308/328s (to varying degrees) and I understand that basic tasks are
do-able if you know what you're doing, are brave, or simply foolish.

Even the youngest 328s are a couple of decades old, so
suspension/joints/bushes/etc will need looking at, and of course there may
be something lurking below the paint

A Corvette is car, a Ferrari is a legend. Buy one and you will never regret
it.

Servicing costs in the USA are MUCH higher than in Europe.

In the US, belts (and more importantly , bearings) should be changed at 3
years.

Valves only need adjusting at 18,000 miles according to the book but don;t
move around too much - the valve seats are pretty hard. Its not a huge job

Rust is your biggest enemy - so keep it away from salty roads & in a dry
garage.

328s are very simple cars - there really isn't much to go wrong. The
injection either works or it doesn't (its Bosck K-Jet as used on many Mercs
so is pretty reliable).

As Paul said, the youngest 328 is now 18 yrs old & so inevitably things like
hoses & *possibly* bushes might need attention.

If you really want a 328 I'd look for an 88.5 / 89 car. The 89s have ABS but
both have a major suspension upgrade over the earlier cars. You can tell an
ABS car by its wheels - convex instead of concave.

For some reason some 328 parts are expensive - even in comparison to similar
parts on 308s. Brake disk (rotors), rotor arms, ignition lead sets,
distributor caps to name a few

Above all you are better off buying a car that sees regular use rather than
a garage queen - its likely to give you fewer problems. Don't be afraid of
higher mileage cars either, there are 60,80 & 100k+ cars out there now still
working well. Just get it properly inspected & use your head when you buy.
