Did you mean new Master Cylinder resevoir, cause the master cylinder on the Powermaster unit does not look new at all. Are you missing the Turbo Shroud or was it removed for the picture?
Looks to be fairly stock other than the transmission upgrade. The 2004r transmissions are very solid so curious as to why it was changed on this car when no other performance upgrades were done?
6K is probably right in line for this condition/mileage car.
EDIT: Is that a factory moon roof (Astro roof) or aftermarket? If factory you should advertise better as they are more rare.
master cylinder is not correct, not powermaster, changed
True, someone's done a vacuum brake conversion on the car, which is a very common and popular mod. The powermaster brakes are electric and problematic when the electric pump fails (can you say no hydraulic brakes at that point). I myself have a hydroboost unit (same hydraulic principle but uses power steering pump) sitting on the shelf ready to change out my powermaster unit in my 86.
Sooo.....Bottom line, to the OP, you might mention that a vacuum brake conversion has been done on the vehicle, but its not a deal breaker by any means and some will consider it a desired upgrade.
Now I'll really upset people, mine runs good and I'd blow any Maurader off the road unless it is supercharged, thern it's neck to neck, mine will run in the 11/12's all day long with $400.00 dollors of mod's and I love it so much it'll be mine until I die, then it's my son's.
