Pre-purchase walkaround
2004 Ford Mustang (SN95/New Edge)
1,900 miles · asking $42,004
Five-year cost to own, maintenance and fuel
~$17,000
The last of the New Edge Mustangs before the retro S197 arrived, offered as a base V6 or the GT with a 4.6L 2-valve V8. Money mostly goes to intake manifold cracks, ignition components, and worn suspension bushings, with the V6 cars being cheaper but less desirable.

What to look for on this one
Every used example of this chassis has the same questions. The bands show when each tends to surface; the gold line is this car at 1,900 miles.
Plastic intake manifold coolant crossover cracks (4.6L)$550-$1,600 if not done
0typical window 60k-120k · this car: 2k, ahead of it150k mi
The composite intake manifolds on 4.6L 2V engines are known to crack at the coolant crossover, a very common failure on these years. Coolant leak at the front of the intake, overheating, or coolant loss with no obvious puddle.
8.8 rear axle whine and clunk$1,100-$2,180 if not done
0typical window 80k-150k · this car: 2k, ahead of it150k mi
The solid 8.8 rear axle develops bearing whine and worn clutch packs (Traction-Lok) with age and abuse. Whine on decel, clunk on takeup, or leaking pinion/axle seals.
Rear frame rail / torque box rustpriced only if found
Condition-driven, not mileage-driven, so it is not in the totals and inspection is the only answer. Flaking or perforated metal around rear frame rails and floor, especially on northern cars.

Hand this to your inspector
A $300 inspection against this list is the best money in the whole deal.
01Pressure test the cooling system and inspect the intake manifold crossover for coolant seepage (4.6L)
02Watch a cold start and idle for surging or stalling, then verify cruise control engages and holds
03Scan for stored misfire and speed-control related codes
04Put it on a lift and check rear frame rails, torque boxes, and floor pans for rust perforation
