I agree with Nicky's contention that Cadilacs in general can be a money
pit if it is not maintained properly. Have a qualified Cadillac
mechanic do a through inspection of all the major components of your
prospective vehicle. This will give you an educated opinion about
whether to purchase or not.
I own a 1995 Seville STS that I bought used a couple years ago.
Initially, it gave me problems that I inherited (sp) from the previous
owner, so I spent the money to get it in proper shape. Now I do not
have to worry about it so much. Cadillacs can be expensive to
maintain, but the ride is great on the open rode, particularly the STS.
The STS is more like a Stock Car, and on the open road can handle most
other cars. The STS is a fun car to drive. It is a high performance
vehicle. It has a Northstar engine, which tends to leak oil, but that
is normal for this engine. The cure for this problem is to have the
upper, middle and lower gaskets replaced.
The Northstar can last at least 250,00 miles if you take care of it.
Keep your engine oiled, your cooling system maintained, and change your
transmission fluids every 30,000 miles and you will have a car that is
difficult to part with.
