2003 Toyota Celica GT 2dr Hatchback (1.8L 4cyl 4A)
It surprised me how well Celicas retained their value, then I drove one! I'd been eyeballing them for a couple months and when I finally had enough cash to buy it outright, I didn't hesitate to scoop one up. I disagree with the sports car classification but it is quick. Having owned a junky '97 Sebring and still owning a '70 El Camino, both problematic, it's great to have a car where I only need to do routine maintenance and it runs like a top. My Celica has almost 94,000 miles on it and I can probably get another 100,000 out of it before it starts to really fall apart!
Easily the gas mileage, the reliability and the handling. It's a well-built car all around.
The engine could use more guts, but it's probably moot since Celicas aren't manufactured anymore.
