I work for a car leasing company in the UK, www.carlease.uk.com , and would very much like to understand the take up of alternative fuel cars in the USA. In my experience vehicle technology changes in the USA flow across the Atlantic to us here in the UK. It seems to me reading through the threads in this forum there are numerous practical issues being explored and I would appreciate any feedback from daily users of these cars to offer me some advanced information. Our business is beginning to offer these types of vehicles so the better informed we are the better customer service we can offer, looking forward to your replies and help.
