There must be a typo somewhere in your comment, I don't understand how 350/week for 5 months is better than 500/month.
I guess what GP meant is that you can rent only whenever you need it, as opposed to 500/month for _every_ month you own?
I actually meant “rent the car for X month”, but I made some mistakes here. First, I took the exact numbers for the calculation, but rounded them generously in favor of owning the car in the post. Second I made some sort of mistake, doing the math, so I’m still slightly off. The correct math:
The smallest golf on the list is 579 EUR/Month, that’s 6.948 EUR per year. Renting a Golf at starcar costs 1436 EUR for the month of August. That’s 4.84, just shy of 5.
That means I can rent that car for ~5 month and still come out ahead.
