The only body damage on my black 01 is it appears that someone tagged a mailbox with the passenger mirror. The actual mirror is fine, but the painted cover is cracked and missing a 3"x3" triangle off the lower outter edge.

I'd like to replace it and the cheapest that I've found on ebay for an 01 is like $165.

Which years would work (power/heated mirrors) and can I just replace the outter cover or do I need to replace the whole thing?

Thanks.

00 and 01 will work and I think the outer cover is just a snap on piece that was installed after the mirror mechanism went in...

Try ebay.co.uk for some of those mirrors for cheaper or car-parts.com for your local scrap yards... you may even find one that is same color as yours.
