Subaru, Honda, or Toyota. Change oil every 3000 miles with regular oil or 4-5000 miles with synthetic. Completely flush coolant every 2 years, use regular green ethylene glycol(check compatability with cooling system). Take care of the small problems as they occour so you don't have a big bill all at once.

Subarus don't have much coolant capacity so make sure its full and not leaking. They are all-wheel drive so thats a plus.

I haven't worked on Suzukis, but I can say that Mitsubishis are expensive to repair. The other cheaper cars usually don't last as long.
For example Kia Sephia with a bad heater core at 30,000 miles. It can be hard to get things covered under their warrenties. "Acceptible oil leakage" What the hey?

German cars have nice features but are high maintenance and have constant small and medium sized problems. VW TDI diesels get great mpg but take special oil and don't have a spin on oil filter. The splash pan under the engine is a PITA to R&R.

These are a few observations from 20+ years of twisting wrenches for a living. Good Luck!
