Garden route, how long?

I want to drive, at leisurely pace between Port Elizabeth and Cape Town, not doing more than about 3 hours of driving a day. How long would this take?

Thanks

2 days at 3 hours per day. It is about 7 hours drive from CT to PE.

HI...
I drove through from Jeffreys Bay to Capetown in around 7days, but sent a day in plett, two days in wilderness, two days in knynsa. Try to stay in Buffalos Bay at the hostel on the beach. Take as much time as you can, its such a beautiful, don't rush it
