I spent almost a year researching the Transit series of vehicles and the TC imperticular, talking to owners and dealers in the UK to help make my buying decision. I use my TC to earn a living. I'm a medical courier and the TC is exactly what I needed. Plenty of space, easy access, secure and agile. The rear powerpoint I use for a 12vdc cooler to carry specimens. The TC has plenty of power even carrying a half ton of copy paper. I can run 85mph as easily I 45mph. Cost per mile is less than 14 cents and averaging 23mpg. Generally run 160 miles per day, 5 days per week.
The TC was not designed to be everything to everyone, not even close.
I really don't understand why you would spend all that money and not understand what you purchased.
