Wow, that's a very nice car.
Of course you are very proud to have such a beautiful car.
It's way much older than my D.
My DeLorean is one of the few (approx. 100-150 cars) that have been painted. Not factory though, as the factory didn't have a paint street nor a permit to set one up. Painting was permitted by the big boss, but dealers had to take care of the job.
My Pontiac is a late 95 model and therefore designated as being a 96er.
Most of the problems were in the first 3 (warranty) years, fortunately.
A picture of the car is in my oil pressure switch thread, as per your request:

If I'm correct these cars were built in Austria.
A week ago I have replaced the spark plugs; man oh man, that's a hell of a job on a 6 cylinder car. Took me about 3 hours for the rear ones.
One of the major changes I made was rewiring the main lights. The factory wiring was way too light to provide good power to the lamps. I rewired using 2.5 mm2 wire and for each unit its own relay. That improved the light by 50%. I also made all units work when the high beam is turned on.
I started doing my own maintenance after I found that the workshop that did service the car previously, never replaced the oil filter (it still had the factory sticker on it after removing). I knew why: the filter seized so tightly that it ruptured totally upon attempts to remove it.
Now I actually don't need a big car like this one, but it drives well, is comfortable and most of all it's worth nothing for trading in. So I keep it as long as possible, at least until the engine gives in. An overhaul is a bit too much for the car's age and for me.
Attached is daylight picture of my D taken while on the test track of the former factory at Dunmurry N-Ireland. I seem unable at the moment to find a decent picture of the Pontiac, other than the one in the other thread.
