To be brief, 5 HP, and a few nuances that can be expensive,
Key fobs, EBCM, TPMS, all are higher replacement cost on 2000.

That would be a "yes".

The '04s also got some good nuts and bolts differences, some of which have turned out to make some replacements/upgrades a bit cheaper for me than for older models. I'm sure there are just as many things I haven't found that will be more expensive to deal with. I like to buy the last model year of a particular body-style or platform. The engineers have usually worked out the major issues at that point, even if replacements are more expensive you're not as likely to need as many.

 

Thanks everyone for the info, it was very informative. I love having this resource, thanks again.

 

Thanks for all your info, it was very helpful.

 

That's funny..........

 

You also get an increase of 25ft/lbs of torque on a manual 2001+ C5
