This was my first car, and I still own and like it a lot. So far, the only repair I had done was the front left brake caliper. A seal went bad allowing water to get to the inside causing rust so it didn't release all the way when I let off the brake. Labor is whats most expensive. You can find cheaper refurbished parts from Volvo, which is what I did. Its a heavier car, so it goes through tires faster than others. Fuel economy is okay, it seems to do better with premium. The body and appearance is fantastic. It still looks new 11 years later. I'd like to get larger factory Volvo wheels, as the 15" wheels it came with look oddly small compared to the larger body.
The heated seats. The engine power, so long as you keep it maintained. Large online community of enthusiasts to back you up if you have problems.
The little electrical problems people seem to have. A manual would be nice. The automatic has a torque limiter, I believe.
