560 SEC / 380 SEC
 

Hi Guys

Im thinking of buying a 560 SEC or 380 SEC
Will be great if you can give me some info about :
reliability, things to watch for , which model is better and any other useful info

THANKS

I'm by no means an expert on these but, from what I've heard, the 380 engine had issues with timing chains. I'd go for the 560, assuming it's a good example.

The 380s are insanely cheap because they're not nearly as good as the 560s. Find a late model 560 that's one, or maybe two, owner with records and in very good condition. Don't talk yourself into "it just needs seats", etc because there are too many good ones to buy. Ask if the timing chain and guides were done - if not, that's the first thing you'll need to do. Check to see if the AC is still R12 or converted to R134. I way prefer the R12 on theses 80's cars.

8bender:

An '84 or '85 380 in good condition, low miles, etc., could be the best buy. The early engine timing chain matter is in the past for those years, and should you wish, a 420 engine is a bolt in (both are M116) if the original injection system is retained. The 420 injection could be used with a change of some of the wire harness.

From the standpoint of the basic structure of the car, suspension, driveline, etc., 380s and 560s are essentially the same. Detail differences from year to year. Larger front brakes on 560s; can be retrofitted to 380s.

As with real estate: condition, condition, condition.

Thanks guys
Any years are "the" best years to buy , or are there any years I should avoid?
Thanks again

560SEC all day! In fact, according to a now deceased PP member here, JimB., when I asked which year to look for, he said 1991 - hands down.

any known issues / attention i need to know when im checking a 560 SEC?

Thanks

WAY more power and torque on the 560, unless I found a reeealy nice 380 at a great price, I'd want a 560 all day long.

I'd only buy a West Coast 560SEC, from So. Cal. You're going to pay more, but you'll likely find a far better 560SEC in So. Cal., than you will anywhere in the Country - outside a climate-controlled museum/garage setting for one. These are now 25 years old, so you should be very discriminating, and willing to travel for the right one.

But that's just my preference(s). ;)

The 560 had the more reliable engine, along with more power and torque. Gas mileage will not be great. Things to look for are rust, operation of all the luxury goodies, and rust, especially in the northeast. Condition is more important than specific model year or mileage. Also, timing chains and guides are a wear items on the V8's. The overall engine can last about as long as a similar era diesel, but will go through chains and chain guides which should be replaced every so often. I don't remember the exact interval but I think it was in the area of 130,000 miles.

thanks guys
