Just started researching 5-series wagons. A 1999 through 2002 would be in my price range. I am curious about the DECREASE in power going from the 1999-2000 528iT to the 2001 525iT. The 528 has 193 hp/206 ft-lb (7.9 sec 0-60) vs the 525 which has only 184 hp/175 ft-lb (8.8 sec 0-60). These figures are from Edmunds.com. I would not have guessed that 9 hp could shave almost a second off the 0-60 time, but the 528 does have disproportionately higher torque which would explain the better acceleration. Curb weight is listed as the same.
What improvements in the newer 525iT would offset this significant decrease in power? Would an older 528 be more desirable than a newer 525, given comparable mileage, options, condition, etc.?
