Purchased this vehicle used certified. Initially skeptical as vehicle was already 4yrs old and 2000 was the intial yr for this model. However, unit only had 25K miles. I've been extremely happy with the vehicle. It's paid off, and has had minimal problems during ownership. Minor repairs included internal thermostat replacement, exhaust joint component replacement, CD player, and headlight replacement. All repairs were covered under warranty, but would have cost < $300. Recently, I've noticed some minor oil spotting and some interior lights (buttons) that are not lit - most probably a fuse.
Woodgrain interior, leather, roomy but sporty, great gas mileage, fast, reliable
Having driven the newer version of the S40 (new body style), I prefer the interior style of 2000-2004 bodystle. However, the model that I own has the woodgrain interior. Most pre-2004 models have a less ornate interior design and are less appealing.
