I don't think you can get much safer than a Subaru, especially if you are going small. But, you might say I'm biased, b/c we have 3 of them. My first car was a 1980 Toyota SR5 coupe, used. Our son's first car was my husband's 288,000 mile 2003 Mazda 6, V-6 manual. It was 11 years old at the time, but had been immaculately maintained and still looked sporty. But, my 2005 6 spd manual Xterra hit 300,000 miles, and we decided it was time to upgrade the "family" car as well, and we decided that replacing the Mazda with the Xterra would be the smarter way to go. The mpg weren't much different, and visibility was better in the SUV (everywhere we go is on the interstate with semi-trucks, or rural with deer in the ditches). It looked much newer than it was, and much newer than just 2 years newer than the Mazda. Sold the Mazda, gave him the Xterra. A few months later (at 310,000 miles) the clutch finally needed replacement (original clutch) and it would have cost $1700 by the time it was said and done... (trust me, many hours of labor on this). Rather than invest it into a 310,000 mile engine, we sold it to a backyard mechanic who could do his own labor, and started shopping.
Son ended up with a 2007 Impreza. It's an automatic, and I'm glad, simply b/c it's way too sporty and he has become a Subie fanatic. Tempting enough without the manual on it.
Personally, I drive an Outback, and my husband replaced his Mazda with a Legacy. Prior to the Xterra, I had a Forester. My son even mentioned to us "too bad you sold the Forester way back then." Our daughter turns 16 this summer, and we plan to hand the Legacy down to her. Not sure what husband will want to do for himself. My son wants his next car to be a WRX STi. Surprise. LOL
I will tell you this... in the rain, I would not want to be driving any other vehicle. Ever.
If not a Subaru, we would have been looking at Nissans or Hondas, most likely. But if you've never driven a Subaru, give one a try, and slam a few doors. Not many doors are a solid as a Subie, and as safe in a crash.
Regardless what you do, research the insurance before you buy. Teen boy insurance will blow your mind.
