It's a bold idea - I don't know if I dare do it as the car has a some kind of warrantee on it - 3yrs I think.
I do have a friend who had his Passat Estate remapped to 155BHP but he drives a lot in his work and some long distances to Scotland from the Midlands too - I've been with him -it's an awesome drive. I imagine it would make a big difference - I'll have to weigh that one up.
I've just asked Honda for a price on the towbar (including fitting & electrics) and it's astronomical - £789 fixed, £860 detachable! I want to ask here about the options - surely that price is completely unreasonable.
