I bought one for my wife. She loves it. I ended up buying one for myself as well.
Go for the "long range" option. Mine will start from a few blocks away.
Also, check out the install shop carefully, get references for a good track record of plenty of installs.
This install can really mess with a modern car, especially with security systems.
My advice is to pay extra to take it to a place that is known to be competent. I asked my Acura dealer who they recommended. I called a few dealerships and got the same answer.
I've been really pleased with the result, and the wife loves it as well.
