couple questions (new buyer)
 

I was curious if a cx 5 will tow a jet ski with the factory installed class one hitch (new to towing). In addition are the following items worth installing on your car when purchasing your car through the dealer or better off doing it on my own:
1. remote start
2. hitch / towing package
3. roof rails

Thanks!

I would think it best thru dealer as this would be covered for warranty, otherwise Mazda will blame anything because of all the aftermarket installation.

The towing: make sure that an external transmission cooler is installed! ---- if not don't do it.
