I have been burned by regular hire car companies from Heathrow before with hidden charges, rude staff and long delays. The whole process from Traffic Self drive was a breath of fresh air. Met on time at the airport, paperwork all ready, process clearly explained, car park ticket handed over with number plate recognition already sorted out. Process for Dartford Bridge explained, very professional and courteous service throughout. I found this company via referral and will be the only company I look to book with in future. A high degree of professional pride in their company. Highly recommended.
