The problem is that we are out of the UK for at least 3 to 4 months over winter every year, and this might extend to almost 6 months sometimes. We considered buying a new car and placing it in storage during our winter sojourn in India (as we used to do with the Subaru) but upon further consideration decided that we could save on this needless expense. Obviously, leasing a car was not an option given our plans but long term rental certainly appears to be. My initial inquiries about that resulted in positive responses from 2 companies, Apex Car Rental and SIXT; Apex in particular have understood the situation correctly and have come up with very acceptable solutions, assuming the quotes are suitable.
As we have not dealt with these companies before, I request members to comment on their status and service.
