My 2000 E39 528iT is in real trouble – it’s consuming ~10 ounces of coolant per day, largely because I have an 80 mile daily commute and I like to drive at 80, cuz I can! I’ve clearly got a crack somewhere – head, head gasket – and I can’t see the wisdom of sinking $ into a 17 year old car with 139k on the odo. I’m in tight shape cash-wise, and I’m finding a few 2009 5 Series Sport Wagons with mileage in the mid 50’s and prices in the $15 - $18k range. I love having a wagon because I like having the utility of cargo space in a vehicle that drives like a sedan. I also like driving something one doesn’t see on the road every day- like the wagon and my M635... Can anyone share whatever knowledge you have re the pro’s and con’s of the 2009 5 Series Sport Wagon – and what I should be mindful of if I buy a car with ~50k on the odo and add ~40k per year for the next 3, 4, 5 years? Any insight would be most appreciated.
