Thanks guys for your replies!
My car is a 2004 Semi-Auto V35 coupe. I want to buy a new jet-ski and really that's all i want to tow with my car. I really dont want a tow bar permanently visible on my car, so i did a bit of looking and there is a company in the states that make a kit for the Infinity G35 which is the kit that will fit my car.
(see link below). Its a two piece kit which means it will still look good when not towing as you can remove most of what is visible on the tow kit for normal driving, cruising etc. The only problem i have now is that etrailer.com WILL NOT send outside of the US and some other related states.
I wish i knew someone in the states that i could have it sent to and then have those people send it on to me. do you guys know of anyone that might be able to assist?
