I do this regularly and, over the years, have used everything from a 7.5ltr. Ford Ltd. Wagon to a Smart car! Now a T5 Lwb Autosleepers.
Frankly, except in snow, it is overrated - there is a worse climb in Torquay and on Skye.
Drive steadily, watch for the last hairpin from the Kishorn side and enjoy the view from the area at the top.
Only warning is, be sure the top is clear of cloud as it is that section which is dangerous with drops from the side, usually at the edge of passing areas!
