2002 BMW 5 Series 525i 4dr Sport Wagon (2.5L 6cyl 5M)
Love driving the 525 wagon. It has the utility of an SUV with better gas mileage, lower insurance rates, and great handling & performance. Always have sufficient power when needed. Originally bought the wagon for our dog (in our 20s, no kids), but now wouldn't go without a BMW wagon! Would have never expected strangers to stop us on the street complimenting a wagon, but this happens frequently. We're already planning an upgrade to the '08 535xi Sports Wagon!
Tons of space, but never feels like you're driving a large car. Seats fold down flush and have always been able to carry long & oversized purchases from IKEA, Home Depot, etc. Heated seats always nice. Cargo net behind rear seat that unrolls and secures into ceiling to keep dog in back.
Cupholders are lacking, but bought a nifty aftermarket cupholder that folds down into the center console.
