My son is thinking about buying a 1986 740 turbo with 126,000 miles on
it.....asking price is $1700...
I went with him to look at the car and it started up nice but has somewhat
of a lousy idle...it will idle at 750 and go up to 1000 for a few seconds
and drop back to 1000 and feels like a miss while idleing....but it sounds
good when you rev it up...
We haven't taken it for a test drive yet because I wanted to get the group
thoughts on this car....buy or pass?.....I have a 93 940 turbo with 179,000
miles on it and runs like a dream....
 
Buy it, then give the inlet tract (from filter to manifold including Idle
Air Control Valve) a thorough cleanup then reset throttle switch if
necessary.

Cheers, Peter.

The idle problem is probably a cracked vacuum line or a dirty IAC valve or
throttle body, none are too difficult to take care of. Price depends
entirely on cosmetic condition at this point, the mechanical stuff can
always be fixed. I suggest having a mechanic look it over if you're unsure.

Probably different in other places but 86 was the year leaded petrol cars
ceased sales here. Right now lead replacement petrol is drying up and many
don't run quite as nicely on unleaded or even premium unleaded. That's part
of the reason pre '87 cars are dropping in price quite quickly. Some good
value I reckon.

Assuming he's in the USA this won't be an issue, Volvos here were all made
for unleaded since at least 1975.
