I drive an '97 Subaru Legacy. Far as I know, it still works perfectly.
Lately, there's been a bad exhaust smell around the car when I park and get out. I can smell it inside the car on occasion, but not often. But every single time I get out, it's there, right in the immediate vicinity of the car on all sides.
A mechanic in passing said he "didn't smell anything he wouldn't expect from a car of my age," but he didn't really look at it at all.
The smell is not super-strong, but it's strong enough to irritate me.
