Yes, though buy a small panel van so you can discreetly sleep inside and stash all your gear in there. Even though public transport is pretty good in Yurp, it's a hassle to travel a lot (and being mobile due to the weather), not to mention luggin' all climbing and camping gear.
Long term rental cars might be also an option... but what ever you do, is get a good insurance, so that when your gear gets stolen, you can buy new stuff and not loose many days...
