1)Is the garage currently just framing?

2)What is your budget to finish?

If it is currently just framing you'd be smart to add additional electrical outlets at this time they are always handy at the sides of a garage wall.

The melamine "slatwall" makes for a clean and striking wall with easy upkeep though you're sol if you ding it up becayse it is tough to repair. Also has poor insulating qualities if that is a concern. And rather expensive per sq. foot.
Same with the fibreglass wall panels.

They look nice though, no doubt about it.

I ask because I'm a builder/remodeler and have finished lots of garages. Garage sidewalls seem to take far more abuse than your living areas. That is why we have primarily used drywall--easy to repair if damaged--good insulation--easily paintable--if our clients normally hose out the garage floor we will use "blueboard" much more water resistant than reg. drywall. And it is less expensive. A good quality primer and satin finish enamel gives a great look. rather inexpensive.

One of the best looking we did was drywall with 8'' tongue and groove clear siding over the top finished with a satin urethane finish up to 8', then the additional wall space above about 12-16'', had mirrors to the ceiling, angled out about an inch at the top. Improved the overhead lighting and really showed off the cars sitting on the tiled floors. Tiled floors had 2 diamond plate "wheel strips" about 16'' wide for the cars to sit on. This was for a 4 car garage for a custom home. Architect/designer specified this for the house plan. Awesome and rich lloking when trimmed out and finished.
