I am nearing the end of the 3 year lease on my 2000 S80. To date, it has been a very reliable car and I am think about buying it at lease termination. My only concerns is that it goes through light bulbs (specifically front headlights). In two and half years, I must have gone through 6 or 8 bulbs. Yeah, I've heard the DRL line ... however, never had that occur in my other DRL equipped cars.

Question: should I be concerned with the electrical system of the car and NOT purchase an otherwise reliable car? Or do the light bulbs have that low of a lifespan. I have about 30,000 miles on the car.
