One small car from Cagliari airport, Fri 30 Oct to Sat 7 Nov. Short version: book Avis at Cagliari Elmas (CAG), pay with the Chase Sapphire Preferred, and say no to their extra cover at the desk. About $155–195 for the whole 8 days, plus fuel.
Your trip has two awkward times. You land at 07:20 on Friday and want to be driving by 08:00. On the last morning you need the car back by 07:30 on Saturday for the 09:20 flight. Most desks at CAG open at 08:00.
These are live prices from Mon 26 Oct for 30 Oct 08:00 → 7 Nov, in US dollars, as Avis and Kayak showed them. The Avis rows are actual totals from the Avis checkout page, with every tax and fee included. The Kayak rows are the cheapest “from” price for each company. Prices this close to the date move daily.

Taxes and fees on the Panda were $49.46: airport surcharge $19.43, local tax $8.92, registration fee $21.11. On the Captur they were $54.81. Totals marked “≈” are my estimates from the same fees; the two bold ones are exactly what Avis showed. Unlimited kilometres, theft protection and basic collision damage waiver are included. A pay-now booking costs $50 to cancel, or $150 within 24 hours of pick-up, so pay at the desk: it's only about $15–20 more and you can cancel for free.

Maggiore (also Avis group, open before 08:00) didn't show up on Kayak. Check maggiore.it if you like, but expect prices close to Avis.
You have hand luggage only and two people, so any class fits. What matters is the roads: hairpins up to the Golgo plateau and through Baunei's narrow streets, the Genna Silana pass in the dark, 5 km of washboard dirt road into Piscinas, 1–1.5 km of dirt track to the Goloritzé trailhead, and long fast stretches on the SS131 and the new SS125.
≈ $195 at desk · $174.82 pay now
Sits higher off the ground than a Panda, so it's calmer on the Piscinas washboard and the Golgo track. More power for the climbs, quieter on the 2–3 hour transfer days, and it holds 2 large and 2 small bags. Costs about $40 more than the Panda.
≈ $156 at desk · $142.46 pay now
Sardinia's default car: narrow, nimble in village streets, cheap to run, and it handles the dirt roads fine if you go slowly. A bit noisy and slow on the SS131. A good choice if you'd rather save the $40.
≈ $230 estimate · $166 + tax
Worth it only if neither of you wants to drive a manual on steep hairpins. Avis has few automatics, and “or similar” may still mean a manual if you don't book this class.
Skip the mini class (Aygo): it saves only $3 over the Panda, has 3 doors, and struggles up the Golgo hairpins with two people.
This is where most of the money is saved or lost. Avis Italy charges €32–58 per day for Super Cover, the counter product that takes your excess to zero. That's €256–464 for 8 days, two to three times the price of the car. Your card already covers the same risk.
“If the Rental Agency, outside of the United States, will not allow You to decline their CDW/LDW coverage, then this benefit is secondary to the Rental Agency’s CDW/LDW coverage.” Chase Sapphire Preferred Guide to Benefits, Auto Rental Coverage
Avis's checkout says it holds up to $300 on your card. Italian desks often block more when you decline Super Cover, sometimes the whole excess. Make sure the Sapphire has €2,000 or so of free credit. The hold is released after the car is back, and that can take up to two weeks.
Avis charges the excess to your card first, and Chase pays you back weeks later.
Some Italian desks ask for proof that your card covers the car before they let you decline their cover. Avis usually doesn't, but it costs nothing: download a letter of coverage from chasecardbenefits.com (or ask at +1 800 350 1362) and keep the PDF on your phone.
If you'd rather never deal with a claim, the alternative is Avis Super Cover at the desk (€32–58/day). That's peace of mind at roughly €300–450, and the Chase benefit no longer applies.
No young-driver fee (that's for under-25s) and no maximum age to worry about.
Valid in Italy as it is. You don't need an International Driving Permit. Bring the physical card: a photo won't do.
A real credit card in the main driver's name, which is what Italian desks want for the hold. No foreign-transaction fees. If the card machine offers to charge you in dollars, always choose EUR.
He needs a short rental at CAG: Fri 30 Oct 08:00 → Sat 31 Oct about 18:00 (Option A: he drives back from Gorropu and returns the car at about 17:15). Kayak's cheapest for those dates on 26 Oct:
| Company | From | Note |
|---|---|---|
| Centauro · Italy Car Rent · Record go · Viaggiare · B-Rent · Wheego · CarWiz | $13–19 | Mostly off-airport. OK for a Saturday-evening return, but expect hard selling of their cover at the desk. |
| Locauto | $34 | In the terminal. The sensible pick for him. |
| Alamo · Autovia · Europcar · Galdierirent · Ecovia | $38 | |
| Noleggiare · Hertz · Dollar · Drivalia · Sicily by Car | $41–47 | |
| Avis | $284 | Strangely expensive for 1–2 days: avoid. |
A Saturday-evening return falls within normal desk hours (most are open 08:00–23:00), so any company works. If he picks Option B instead (leaving Cala Gonone at 03:45 on Sunday and dropping the car at about 07:00), he needs Avis, Budget or Sixt for the early return. Remind him: on Friday, Locauto and the others open at 08:00, so you'll both be driving away around 08:00–08:15.
Sardinia has no toll motorways. The SS131, SS125 and SS554 are all free.
The old centre (Castello, Marina, Stampace, Villanova) has camera-enforced restricted-traffic zones (ZTL). Park outside them and walk, especially on Thu 5 Nov for the Sella del Diavolo (Marina Piccola is fine).
“Autovelox” cameras are common on the SS131, the SS125 and through villages. Usual limits: 50 in towns, 90 on ordinary roads, 110 on dual carriageways, but check the signs.
Dipped headlights are compulsory outside towns, day and night.
“Fai da te” (self-service) is cheaper than “servito”. Stations are rare in the mountains: Baunei is the last one before Dorgali, and there's none on the SP71 Costa del Sud (fill up before Teulada).
Blue lines: pay (machine or app). White lines: free. Yellow lines: residents or disabled only. Sinis beach parking is still paid on Mon 2 Nov.
Into Piscinas via Ingurtosu (5 km of washboard) and to Su Porteddu (about 1.5 km): 20–30 km/h, keep off the deep ruts, and expect stone chips.
Goats, cattle, pigs and boar on the SS125 and the Golgo plateau, especially after sunset (about 17:20). Slow down on blind bends.
