Got two cars to choose from. A pretty loaded 2000 Grand Prix (heated leather, sunroof, 3.8 non-supercharged engine), or a 2000 300M. Both have pretty close to the same mileage (well, kilometerage, since I'm in Canada).My needs are commuting type driving, but I want to do it in style. :) Otherwise I'd be getting an Echo or something. About 35km (20 miles?) each way, on a freeway with average speeds around 80km/hour (50 mph). Very little stop-and-go. I've got two kids (8 and 6), but we've also got a mini-van, so I'd be the only person in the car 80+% of the time. But I still want 4 seats, if not 4 doors.Any comments on reliability, being a daily driver, etc? I don't really plan on modding at all... I'm almost 40, so I think I'm past that. :)Thanks in advance!Clint

They'll both be excellent, really. We've had several 3.5L LH cars, and really they've performed wonderfully, but I know a GM 3800 is just as good. We get about 20 mpg around town, which is pretty impressive for a car as big and powerful as a 300M. The back seat may be an area where the M is better than the GP, but I don't have a GP. Just based on looks, I don't think the GP wheelbase is quite as long. For one thing it's not a Bonneville.I don't think there's any question that the GM transmissions will last longer. You can get to 200K miles with one of those divetrains without any trouble. 300k miles is not unusual. The 3800 also doesn't require timing belt changes.The 300's got more hp and it's better looking. So there you go.

Opinions wanted: 2000 Chrysler 300M or Grand Prix GT?

For your sake I certainly hope so. I would hate to see you have to get a new trans just because the fluid wasn't changed. Also be damn sure whoever changes it be it you, the dealer, or another shop uses ATF+4 fluid unless you like the rough shifts and reduced trans life caused by Dexron with or without lubeguard added.

And don't forget to change the differential fluid periodically too.

75W-90 or 80W-90.
