Actually if I am going by family and friends I'd say the GMs last longer, most people I know with Fords don't have them very long. That said all i can really go on is my personal experiences, there are Fleetwoods, Caprices, Impalas, and Roadmasters with more than 200k-300k and run great and many on stock engines. Right now I have a 98 Ranger, 00 GTP, and 93 Fleetwood. The Ranger needed a new engine at 100k and now needs a new transmission at 170k, the crown Vic needed it's second transmission rebuild when I sold it,. needed front end work, had an airbag light, and the bolts that hold the driver's seat down all broke but 1 the fan Speed control didn't work (full or nothing), and had to replace multiple sensors, but the engine as smooth as can be. the Grand marquis had sticking throttle issues at 103k and was showing signs of transmission failure, I bought a 60k mile SHO Taurus and only kept it for 6 hours because it starting throwing a check engine light and codes, my 91 T-bird blew it's headgaskets and multiple brake issues, and the AC was non operational, again had just over 110k when I sold it, my 93 T-Bird blew out it's freezeplugs, had to have balljoint=s and tierod ends replaced on both sides at 83k miles, alternator went out, AC went out, and the transmission was going out and the main seals were leaking oil from the engine (5.0 HO) There is the fun I have had with Fords. Now my GM I won't include my S-10s since they were both smallblock conversions, though I can say at 180k and 205k miules the bodies and suspension were in great shape. My roadmaster only ever needed a thermostat, though my time with it was short (only got to put about 20k miles on it, had 90k when i traded it), Caprice in 50k miles of driving needed nothing but basic maintenence, the caddie is need of shocks and tires and the intermittent wipers don't work, but, from the previous and only owner, has never had a motor or transmission rebuild and is at 160k miles and runs and shifts as good as any new car. Now the GTP, this has been my most troublesome GM, tranny rebuild at 130k miles, AC has a leak, window switch is out and replace both front wheel hubs, though most of that is a direct result of the extra power being channeled through the front wheels. That's a lot of experience and you posted but ONE example of a high mileage Ford and it is great it has lasted so long, but that is but one example I am sure i can find at LEAST 1 chevy or GMC locally that has done the same or MORE. And I stick by it, Ford and GM are the same, you take care of them and they will treat you well, I mean hell, i am not here saying Fords are pieces of **** and GMs rule the world or some similar stupid BS. I mean give it break, don't be so blinded by Ford you have to take poy shots at other manufactures to make yourself feel better or something (or why, I wouldn't know as it's pretty silly). Anywho, I would own either one as both have come a real long way in thast few years especially.
