The E39 needs no introduction and as a proud owner of this rare gem it saddens me to let her go...unfortunately the family have spoken and I will be looking for an AUTO X5d in place of this beast. fcplm

The vision behind this Touring was to create a Touring that offers similar performance to the M5 Touring not available here in North America while maintaining DD civility and great fuel economy of the I6. I average 9L per 100km combined (75% city and 25% hw), pretty amazing for a car with 370hp and 345lb of torque. The stage 1 ESS twin screw, as many already know, produces a very linear and usable torque band, the stage 2+ is even better. (http://www.esstuning.com/products/M54B30-Twin-Screw-Stage-2-%28TS2%29.html)

OH, and did I mention my insurance for this beaut was $780 a YEAR!!! :eek:

This beast started out as a 2.5L but was swapped with the 3.0L M54, along with M5 body kit and the go fast goodies. I imported her from Michigan last spring and have only had to replace all the fluids, swapped the stg 2 clutch that it came with with OEM (for DD civility), and perform the Vanos bearing repair kit, all done at RMP Motors. I also have over $25K in receipts from the PO on the installs.

Mileage: 135k on chassis and 95k on M54

The good
- During the recent Vanos repair, Rocco found a crack on the valve cover and after it was replaced, the engine pulls much harder. Thanks Rocco!
- Everything else works on this car, including the massage chair, although its more tickling than actual massage....
- Needs nothing *rockout*

The Nuisance
- Bilstein rear shock which I find too harsh
- Door dings
- Stone chips on the hood and front bumper
- ESS tuning in cold weather, the car needs to be warmed up before heading out. 3-4min IS required in cold weather. Rocco even called ESS head quarter and they do not have any fixes...
- Some pixels on the dash stopped working, but overall still very legible

Pictures will be posted in a few days after I get the car back from the detailer.

Hoping to find someone that enjoys her as much as I do!!

Asking: $15.9 FIRM to serious buyers only, no test pilots please.

thanks for looking

PS: Also will be selling my S52 M Coupe soon, but thats for another post...prob in the spring
