Carl’s harps are about the height of many semi grands, 72 inches. I might add he also has a lot of beautiful used petite harps for sale, many of which would probably fit your needs well too. I use ZipCar and have driven a variety of vehicles with my harp, and my 74″ concert grand is a very close fit in many (combined with my own 72″ height). Those extra two inches of a 72″ harp would make many vehicles a much better fit, and something like a Style 12, an 85P, a Camac Clio, or a Venus Seraphim would be a relative breeze.

One advantage of a semi grand over a petite harp is that if you later develop a desire to play more classical harp repertoire, the extra strings would be useful. Most semis have 46, which will do the job for most repertoire written (you can retune the low D to a C if you really need it). The extra string of a concert grand isn’t a major consideration for most amateur playing. In addition, many semis have the same soundbox and soundboard dimensions but are just a little shorter. Some are intentionally a bit narrower to make them a little easier to move around and fit into spaces, as well as lighter. Personally, if my budget were unlimited, I’d own a petite harp of 42-44 strings for church and chamber music, plus most rehearsals if the range allows, and save the concert grand for wind ensemble concerts. I’d also own my own vehicle and a parking space, but that’s another story.
