Firstly, great choice on wanting to get involved. One of the best purchases I’ve ever made was my emtb. I doubt you’ll be disappointed! Agree with others comments, but the key is setting your budget. It’s so easy to have your head turned with so much variety. And with an oversupply of bikes now...
Yes Tassie! One of the world’s great wonders. A very special place indeed. I would love to ride there. I live in the UK now but my family are in Smithton. Where are you based?
To answer the OP, I’ll happily hire anywhere that has decent bikes. Couldn’t get my Whyte e-150rs up to Scotland for a work trip so I hired a Trek Rail and toured the Kirroughtree area. Whilst I wasn’t a fan of the Trek when comparing to my Whyte, for £60 it provided 4hrs of mountain bliss
I’ve got a pan roof on my Golf and fitted Thule roof racks with no issue. Maybe worth a look.
Although most of the time, I just take the front wheel off (29”), drop the rear seats and the bike fits perfectly - would think your Fiesta would have similar capacity
