In reply to Wiley Coyote:
I had a complete nightmare with Goldcar - they supplied me with car that had a badly damaged wheel that had a new wheel trim on it to hide it.
The car vibrated at anything over 100 kph so i asked them to come and pick up the car which involved me driving to the bottom of the mountain i was staying on to meet a pick up truck then spending most of the day getting to another airport to pick up a replacement.
They then charged me for damaging the car even though i had only had it for 30 hours and the damage on the wheel was rusty. I had to pay this on my credit card.
The replacement i got offered had a badly nicked tyre so i refused as dangerous. The next replacement was safe but had body damage that i got the manager to record and i photographed.
Took me two months to get my money back and i didn't even get an apology. The tone of the email suggested i got my money back because they couldn't prove i had damaged it because i had time stamped photos of the rusty wheel.
I booked them the doyospain who are a reseller. I now pay extra and go with Avis. When you work out the hidden scam costs for petrol,insurance and extra drivers you tend to find there is not much difference over a two week holiday.
I have used most of the car hire companies in Spain and Goldcar are the only negative experience I've ever had.
