Your wise to think about that!
A few other things?
I have a BendPak XPR-10A-LP. Note this is the only ALI lift that has been mentioned in this thread. Decide how important this is to you. To me it's CRITICAL! BUT I found it added about $600 or so to the cost of the lift compared to non-certified lifts. What convinced me is the testing the lift goes thru to meet ALI spec's. You can watch videos on how they rate them and how they overload them during testing.
I also did NOT want anything on the ground between the columns. So I have the overhead bar with safety shut down on it.

Note it's 137"-145" wide. I also was concerned about door access. I also vote for asymmetrical installation.
This is with a Lincoln LS on it but you can see how much room you have on each side. Of course the downside is the lift will consume more of your shop the bigger it is. Note the angled columns for the asymmetrical install.
No need to worry about 2300 lb on a 2500 lb arm. They have a safety factor built in. I regularly put a Ford F-450-4 door W/4 Wheel Drive which is over 8500 lbs on my 10K lift. This is a BIG, LONG truck!
I have a tennis ball hung on a string in the exact center of the lift. When you drive in put the tennis ball dead center on your hood and now the vehicle is centered on the lift. Really made it quick to get a vehicle in there straight. Then the string/tennis ball is just put to the side of the lift for out of the way storage.
Mine is the LP version. LP = Low profile. What kind of stuff will you be working on? I am a high performance guy and any lowered car/truck will be a SOB to get in the air. I usually put some short 2" X 4"'s under the tires to raise the car up so I can swing the arms under it.
I have a 1957 Chev Pickup street rod that's so low I can't even do that! So I use a floor jack to raise each end up to position the arms. This is a truck that's so low I can't even get my head under the front bumper!
If your budget is $6K you can get any lift you want! Mine was about $3K delivered. Also note there have been several group purchases in the past on Garage Journal too.
