Lots of oil-changes and filter-changes an engine haul should not be needed
in your lifetime.
Depends on how the car is/was driven.
A diesel I think should be counted in how many hours the engine was driven -
A 100.000 mile car has roughly been running for 100 days non-stop
theoretically - not much.
Well, a new exhaust pipe now and then. And a new watercoler-thermostat. Etc.
Otherwise just keep your engine top condition by frequent oil-changes and
For the 320, check to make sure the A/C condenser/evaporator has been
replaced at some point in the recent past. These have been known to go out
at around 75k-80k, and are very expensive (like $5000) to replace. If the
car has 100k on it, and has never had this done, then you may be setting
yourself up for a big repair bill sometime in the near future.
As for an engine rehaul, I wouldn't worry about it if the car has been
otherwise properly maintained. These motors can easily go for 200k-300k with
basic scheduled maintencence and the occasional small repair.
<< I am in the market for a used 1995 SL320. A lot of these cars have in
excess of a 100,000 miles on them. What kind of maintenance should I expect
to perform on a 100k car? At what point should I worry about engine rehaul?
Those are some of the better engines Mercedes ever made and can go over half a
million miles, may be much more. Expect some kind of maintenance. Also, it
depends on how well it was and it will be serviced.
They were designed to last--and show off Mercedes engineering as Japanese
luxury cars were being introduced--unlike the current noisy SOHC with a torque
curve of cheap thrills. If any consolation, they do give you more spark plugs.
While its good enough as leasing became popular and such people dont care about
ownership or how long it will last.
The extraordinarily expensive repairs will be things like the A/C as the
whole dashboard must be removed to get to it. The other thing on this
car is its otherwise fine engine; it's prone to long term headgasket
failure. The block is cast iron and the cylinder head is aluminum; these
expand and contract at slightly different rates and after about 150K
miles the head gasket has had enough of that and fails. The engine's
front cover and valve cover are also prone to small oil leaks.
My '97 has the same fine engine, smoother than later V-6s.
Owning a car like this is like having a trophy wife, beautiful but no
fun if cost is a consideration.
