Worried about keyword stuffing penalty re: URLs

[McTaggart]

I've noticed a potential problem with a mult-location business (this is an example URL - not the actual name of the business)

I sense this is OK:

carsdepots.com/ashford/cars

But then I noticed they've added cars to location part of URL in some instances (they have 6 locations in total and have done this with 5 of them):

carsdepots.com/birmingham-cars/cars

So we have cars in there 3 times (that's the maximum number of times in any URL but it looks a little spammy to me)

I am tempted to remove yoga from the location names, or flatten the URL structure completely - your thoughts would be welcome, or perhaps I shouldn't even be worrying?

If the structure of the URL's make sense, I wouldn't worry about it.

But if,

carsdepots.com/birmingham-cars/cars

is really just

carsdepots.com/birmingham-cars,

then I'd think about addressing it.

IMO, it's unlikely that keyword stuffing the url will negatively affect the site. But, if the rest of the page is keyword stuffed as well, then this could possibly have a negative impact.

Thanks Marie and SErOb - appreciated

I've noted my ideal URLs (from an SEO/usability perspective), so if there is a problem there's a plan b - the URLs are horribly clunky, and may be impacting CTR - yet traffic is increasing on the site, so will leave well alone for now - thanks for your advice Josh.

I wonder whether anyone has carried out any research into this issue? Are there any stats out there?
