I would suggest you choose a 3 wheel cart, easy to push, doesnt tip over easily and easier to store just due to one less wheel than a 4 wheel cart.
I would look for a score card holder, drink holder and not much else. My Clic Gear has a flip open storage are in the handle and a net that will hold a drink if its capped, but my bag also has a bottle pocket and I rarely use the flip open storage.
You may want one that folds up completely just due to your cargo space in your car, but if space is an issue.
My wife and I have one each, one is an old Bag boy, and the other is a Clic gear 3.0, and honestly, I paid $5 for the used Bag Boy, and $85 for the used Clic Gear, and I find that either is suitable and both are easy to push. The Clic Gear does look a bit more classy, but other than that, there really isnt much difference.
Both carts are useable with either a large cart bag, or a stand bag. You might have to adjust the holding straps slightly, but overall its not much bother.
