It honestly depends on your specific market. If I was in your position would do some market research to see how many SUVs are in my market, how much they rent out for, and how often. As that'll give you a good idea of whether or not it'll make sense financially. Plus it depends on how low of an interest rate you can get, because that'll eat up all your profit if it's too high. Also, for your cash car, is that 400-450 net or gross profit? Are you renting it out consistently or just occasionally? Because if that's your gross profit for renting it out consistently, then you might want to tweak your listing a bit in order and get a higher profit (That is of course if you actually want to rent it out more though). As I do have a few cash cars as well, and as an example I have a 2011 Ford Focus that I just added onto Turo in April this year and it's brought in $3,493 so far (so about $1K per month gross profit). Hopefully this helps!👍🏽
