I've used recordgo about 8 times in tenerife mate, there great. You gotta realise though your not going to get a brand new golf tdi or something like that. more likely a kia or renault something like that. I always get the excess waiver, if so the guys couldn't care less what condition it came back in. One of the reps even said you can carve your name into the paintwork and we wouldn't care!
Im always worried about getting stung after using hire cars, but record go have been great.
The cars are left at the airport with a rep and when you drop them off all you do is drive to the airport, park up in their bays, lock the car with the key in and done!
