Please note that the images are not of the actual cars I owned or did own but are the nearest thing I can find on the web! If the auto companies would keep information on older cars on their websites I would have used stock photos!

What you need to understand about GIs and cars when they are overseas is very simple: It costs money to ship the car back. It is as simple as that. No one wants to spend the money to ship a car back so they just sell it to someone else!
If you bring your car over with you it will be shipped back with you. Also, if you buy a car via AAFES while overseas it will also go back with you. It's only when you buy a foreign car that you run into problems. Besides having to pay to ship your car back you also have to pay to convert it to American specs.
I only owned that BMW for a few weeks before I sold it to someone else for $100.

There was something wrong with it as the oil light would always come on. I was not very technically inclined at the time but I did purchase a mechanics manual for the vehicle. I took it over to the base garage and put it on a lift for a few hours... until the guy who worked at the base garage informed me that using the lift would cost me $20 per hour!
I sold the bus a few weeks later and it became someone else's problem!

Within the first couple of thousand miles I hit a deer with the car. Killed the deer and did no real damage to the car except for where the antler scraped some paint. I had to run the car through a car wash to get the gore off the front as well. While in Texas some of my friends "Accidently" broke one of the back pop-out windows. This resulted in a drive to a local wreck yard to find new glass. Through it all that little car never let me down.
Every weekend I would drive the 100+ miles up the coast to visit friends or the same amount south to go shopping or clubbing. I took that car with me when I moved to Texas (fully loaded with all my stuff) and kept it after I left the service! I put over 150K miles on that car before I had to change out the clutch. If my wife had not pushed me to get rid of it and buy a "safer" vehicle that "looked good in the driveway" I would still have that little beast. I got my money's worth out of that car!

To be honest though, I never much liked the Integra. Part of that may have been the need for high octane gas at a time gas prices were quickly rising! Not to mention the huge difference in fuel economy! Still, I drove that car for a few years until I sold it upon inheriting my dead grandmother-in-law's Geo Storm.
