[Closed] Nnew bike rack alternatives

Got a new (to me) car last week and considering the bike carrying options. I used a strap mounted rack on the old car and the straps scuffed the paintwork where they came in contact. I initially planned on getting a towbar fitted but struggling to justify the £430 I've been quoted plus whatever towbar mounted rack I choose. Seems a lot of cash for carrying the bikes on the car 6 odd times a year when we go camping. 😕

Any recommendations for an quick and easy to fit, non-damaging bike rack?
