Honey, if you like the car, get it.
I always like a car alot before deciding to buy it. These Malibus are fairly dependable, but are known for transmission problems. It may last a few years and that is all you get out of any $2,500 car anyway. Any car will be driveable as long as you don't get the engine hot. Check the water and oil everyday before you drive it. Get it hot, you'll have to park it and walk.
As far as buying a foreign car, they are not any more reliable than American cars with high miles, and they will cost 3 times as much to repair, so remember that Grandpa took your car on road trips, not short trips. High miles is ok in this situation and it should go 50K more miles.
