I'd noticed the occasional whiff of exhaust fumes, but last weekend it got severe. so much so, after driving for 20 minutes, I had to pull over and get out of the car. Then decided to drive it straight home.
I've read that chances are that it's a worn trunk seal, and possibly rust holes in the trunk floor. I've had replacement trunk panels for awhile, so that's already booked in to get done.
What I want to know is what else could it be?
I noticed today when I dropped it off at the body-shop that, as soon as I got out, the smell had engulfed the entire car outside and stuck around for a few good seconds. Very noticeable and very hard to determine where it's coming from.
What else should I be looking at?
