True cost of car rental
Quoted rental €30/day. Actual cost: €30 + €40 fuel for a day-out + €10 hotel parking + €15-25 attraction parking + €10 insurance excess waiver + €10 GPS rental = €115/day. Plus the stress of driving in Antalya summer traffic and the parking hunt at each stop.
When car rental still makes sense
You're staying 2+ weeks and want spontaneous exploration. You're a confident driver familiar with mountain roads. You're visiting remote spots (Termessos, Patara) where a driver would just be waiting. Otherwise, private driver wins on cost AND convenience.
