Cheap, good car but some reservations
Rented from Salzburg for a week, with the car provided by U-Save, who are a new company based in Macedonia who are renting out cars which are not in demand in their home markets during the winter. Good price, excellent car in good condition, but the "meet & greet" service actually means you call them, they send a driver to pick you up in the car that you'll be renting (so no luggage transfer needed) which could take 10-15 minutes, and on return you have to find their office a mile from the airport and then wait for the car to be checked in and then a driver found to take you back to the airport in the same car. In my case, I almost missed my flight because this took 35 minutes as they were very busy and understaffed. On-airport return takes 5 minutes - but is usually just a key drop, so there's no confirmation of vehicle state on return and I've had issues in the past with damage being found on the car long after I've departed. The cars were all registered in Bulgaria or Macedonia - no legal issues in Austria, and they had winter tyres as required by Austrian law, but it looks odd. Otherwise no concerns, and the online checkin service worked well.
