I was with a team that drove up there last year. With some care it was driveable, wasn't a 4x4. Best way to describe it is interesting. Out there next week with a few others. We're staying in Surba.
It was fine until about 4 years ago when there was some heavy rain and ruts. Two years ago it was still fine but you had to be careful. No problem if you're used to driving on tracks.
We drove up there this July to walk up the Tourist route. Interesting is the right description. It goes on for a long time, is pretty rough and we made some passengers get out at times on the way down to avoid bottoming out. The car (Citroen People carrier thing) survived though I'd have felt a lot happier having a spare wheel with us.
Well it's not a good road (no tarmac) and it's longish but it's a fairly normal mountain track. If you drive reasonably slowly you'll be fine. Definitely no 4x4 required (I have done it it in Scenic and Up)
A couple of very helpful french lads gave us a lift down the other day. No room in the car so we sat in the boot with the tail gate open. It was a Peugeot 205 or similar not a problem.
Drove it today in a normal car. Road is rutted in places but a 4 wheel drive not required. Only issue was ground clearance, but we were 4 up wiith kit but made it ok.
